I've been reading this book https://www.amazon.com/Conversion-Code-Capture-Internet-Appointments/dp/1119211883/ , I'd highly recommend it
​
A couple of things jump out to me:
1, Homepage lacks trust/credibility, the whole row of facebook/twitter is empty, I just won't trust my money with you
2, Please stop using the slideshow on the homepage, and on top of that, it is too fast
3, The headline "10$ shipping, Canada only" shouldn't be there, it should be your selling points instead. Try "Free Shipping (you can include shipping into prices), Best Deals in "your city" "
