You are off to an amazing start and yes your points are way past beginning.
If you go to Quilters Cache they have SO many squares - some free, some requiring copyright - and many are 10" finished size. I think they also have info on how to change a square to the size you want. And you can sort by size.
Good luck and keep posting your progress!
