Advice on funding my web3 project

I am programming a web3 marketplace, not your usual NFT marketplace, but something quite different(i would like to keep the details classified regarding the same), but I have a good feeling this idea of mine has a lot of profit potential. However I have looked into the costs for hosting all the technology on cloud for running my platform, which includes kubernetes clusters, and the cost cap is really higher than what I can personally afford, so my mind turned into marketing my platform for web3 investors.

My questions include how do i market my platform to web3 investors? how do i get investors? is it necessary for platform to have a convincable profit margin or does it just have to be “working”? And any other helpful advice would be great!

You can look into accelerator programs, you can find some if you search for “web3 startup accelerator”.
