Hosted Hardhat/Anvil Fork networks ??

I have been building a project where we provide cloud hosted fork networks like hardhat/anvil forks, as blockchain mainnet simulators for smart contract testing, ci-cd or dev/staging environments.

Need to know if there is a need for such a project in the market?
Will I be able to generate any revenue?
Will you use it. What network do you connect in your dev/staging versions of dapps?
