Solidity developer needed to create smart contracts for NFT

Job ID: 32880496

Budget: $3,000 – $5,000 USD

I would like to hire you to look over my idea and start work with me.
My goal is to have 10k supply in NFT collection; however I want to upload 2500 each drop. 4 drops altogether.
I need smart contract made to give rewards back to my holders ..
Can smart contracts be made anytime? Or must they be made at the time the images are generated? Can smart contracts be created after NFTs are minted?
