I used to be a picture framer. You should be able to go to any framing shop and get them to make you a couple to the size you want. Ask them to give you the glass and backing board as well and then you can put in whatever pictures you want. You could also measure the pictures and ask them to cut mounts for you. 8" x 8" is not very big so they shouldn't be too expensive and you can choose the moulding you want. (If you get mounts cut, remember that you will need bigger frames to fit them!)
