NFT Design & Nft collections

We are looking for one or more 3d art project designer artists to create and develop Nft collections.
To be able to go into details with you, please I need to know:
1 Have you already created nft collections?
2 If yes, could you send us a portfolio?
3 What would be your prices for creating a nft 2d collection?
4 What would be your prices for creating a nft 3d collection?
5 what and your delivery time for a complex base character ?
If you're wanting to become a paid artist on this project and be apart of the team, that is also possible.
