smart contract nft

I am looking for someone to help me set up my website to sell 10.000 NFT’s. I need to create a payment method including smart contracts in order to sell my NFT’s on my website. I will need the website ready for a launch date with some potential heavy traffic and be fully functional. I will be taking payment via ETH with all my NFT’s being available on Opensea too following mint. I already have the domain and an eCommerce WordPress website (Using WooCommerce). Please let me know your price and any experience doing this in the past? I will be looking to launch this in around 4 weeks time. Thanks.
