Need help for my girlfriend.

Hey guys! My girlfriend recently got her nails done at a place in a mall and the price absolutely shocked me. I decided I wanted to suprise her by trying to learn how to do this myself so that she wouldnt have to pay that much anymore. Does anybody know what the best "beginners kits" I can buy are? I looked on amazon and theres a ton of results but I dont know how much to trust them. I want to make sure I get the best for her. Thank you!
