No problem.
On a budget - I'd go with a simpler route...
A tarp and foam pad can get you a long way. Something like this for $45:

A real tent with bug netting plus an inflatable pad for $170:
​
You would still need something to keep warm with these setups. A sleeping bag / quilt / blanket of some kind. I guess that depends on how cold it gets at night where you backpack.
Nice!
I would suggest a ground sheet to help with the dust. I use a cheap one from amazon .
Any advice on a ground tarp? I know you want it to be a bit smaller than the tent, but is this too small for my 9x7 Coleman?
