Could you give me some tips?

Hello, Im trying to see if i can make some money doing nails because of the necessity 🥲, i want to get more into nail art because my family think i do it somehow good, im not sure if i could because im very shy and i dont really know how to sell or do this.

I know the basics about gelish, but i dont have a lot of material and when i do nails for me it takes me like over 12 hours just 2-3 draws and the left nails are pretty simple (ill adjunct some photos of nails i have done for myself, my mom took them 😂), i dont know a lot about the technique but if u could share me any tips about good-cheap brands to do nail art it would be awesome, also, how to start to sell this?

I have an aunt who is very experienced and works in this, but im so embarrassed to ask her to give me some easy work and took 2-3 hours doing it 🥹. I dont have a lot of money to buy things rn, but i think i can solve it
😅. Thanks in advance!! 🩷🩷
