Nft Auction participation Assistance -- 2

Hello! I am looking for assistance to help me with a Non-Fungible Token (NFT) auction. I need help setting up the auction, but I haven't decided which blockchain platform I should use yet. I also need help to acquire any necessary NFT assets that I need and help to set up the auction if I need it. If you have experience with any of these tasks, I'd be looking for your help. Thanks for your time!
