We downloaded an app (Google Play:Chess Clock by chess.com but I'm sure they're all similar).
There are variations of how the time is managed, some basic wiki reading will probably explain it better than I can.
But what we did in the end was basically set a straight clock, 12 minutes, each player gets 6 to complete all their turns. When it's your turn your clock starts counting down from 6:00, after your move you touch the clock and it pauses. At the same time your opponent clock starts counting down, until s/he makes a move and then touches the clock. Then yours is counting down again.
We found this to be smoother than having X minutes per turn (which you can configure to then roll-over unused seconds or just drop them) and works better with Splendor where earlier turns are simpler and faster, so if you push you can ''bank'' a little more time for the end game decisions.
Ten minutes was really fast, basically no time to think, although one can probably get used to it, so most games didn't reach 15 points. Fifteen minutes always ended with time on the clock, so somewhere around 12 seems to be the sweet spot (for us).

Works great and is a good alternative for clock. If the child is not going to tournaments and budget limit is below sky, I'd not buy a chess clock...for both kids and adults.
I´m sorry about my previous post, now that I read it again, sounds a bit negative. Didn´t mean to putt you off or anything, I could write those ideas in much positive way, sorry about that.
Chess sets, if you want to buy, I advise plastic ones, they are very very durable and cheap, stuff like this: https://thechessstore.com/value-club-plastic-chess-set-board-with-black-ivory-pieces-blue/ (or travel sets, where you can roll-on the board and everything is very portable - is like a tube with board and pieces inside)
The question is that I´m in Europe and I don´t know how things are there to buy material. In my country, you have shops online that they send you material in not much time (if you are a chess club and you buy more than 1 set, they offer you special prices and so on). Thats clear not your case and I have no idea if you have this kind of "chess shop" online in South Arabia even...
I strongly advise you to go here: http://www.saudichess.com/ and navigate around (I don´t speak arab :_ ) . Also make some phone calls to people in the federation or even people from chess clubs in a near city, I´m pretty sure they can help you, at least giving you some clue where to start.
Another option is ask the players to bring their chess sets, this is very popular in American tournaments, but not sure if your players have some at home.
If you only have the place for 2 hours, then perhaps do the tournament in 2 days. I´m not sure how people will react to a 4-5 day tournament, this is quite demanding in my opinion. Perhaps keep it short, in my opinion in 1 afternoon is the best for practical reasons (for you it´s easier to place everything and for the players it´s easy to go do chess for this afternoon and thats it). One day tournaments are very popular where I live and they have usually good participation. Yep, don´t forget inscription, very important. You could do an advert to place in the school with the day, time, inscription process and so on, every chess tournament has a poster :-)
As an idea to solve the "clock" issue, probably everyone has smartphones over there. There´s a number of "chess clock apps", that basically, divide the phone screen in 2 and tapping on it, change the turn. I use those with my friends in bars or pubs to play for fun, could be a solution. (the laptop around, not sure) Talking about this: https://play.google.com/store/apps/details?id=com.chess.clock&hl=es
Good luck! Important, if you have clear the rules, you have more or less set timetable for the rounds and so on, should be fine, but as I said, is not easy. Still, try to make it work and think that this will be the first of many, you will do better in the future for sure
Nice! Download a chess clock app if you don't have a chess clock. This app is a good one for android.
Maybe a chess clock? https://play.google.com/store/apps/details?id=com.chess.clock
Probably an app for that.
I haven't used any of these but there are a few. https://play.google.com/store/apps/details?id=com.chess.clock&hl=en
