Gold coin and bar request!

I recently just bought 6 Russian gold rubles. I have about 33 grams of other 24k to work with. I have a design idea for a big coin pendant. I do NOT want to seriously alter every coin, because they are historic and beautiful, but i AM a willing to seriously alter half of them to fit my design idea. Anybody know anybody? Only willing to alter the jewelry graded ones.
