    Hi there! I'm looking to create a new map based NFT website that allows people to mint / resell new NFTs directly on the site. Probably looking to do it on the polygon network as the NFT's will be low cost so need low gas fees, and to build he site I think React (or similar). I'm looking to start a simple website out to get proof of concept up and running, and then after launching that will be keen to continue to work on the website ongoing with you. Feel free to put a place holder bid if you are interested and I can send you more information about it and we can discuss. Thanks! Mike
