2) Have you found out a suitable payment method for our purchases on the net?
3) My nephew would be interested in taking conversation lessons with you since this will be his first year in high school and he needs to improve his German.

Looking forward to hearing from you,
1. With or without "with" is fine.
2. I'd remove "out."
