Cryptocurrency Mining Website Browser Based

I would like to create a cryptocurrency mining website where people can just login and through their browser they can start mining using their computer's GPU or CPU without downloading anything. Users can schedule when they want their computers to automatically run the system and also an option to black out all screens. Users will then be credited in a form of either BTC or ETH. A conversion is required to USD based on the latest BTC or ETH price. Users are able to connect multiple rigs or accounts running simultaneously all crediting into the same wallet. Users are also able to toggle the maximum processing power dedicated to the mining operation to allow them to utilize other programs while this is running in the background. Key points, our system must be capable of mining from a pool instead of solo mining. Think of a web browser based like NiceHash or Kryptex or Awesome miner. The website owner (me) will draw a variable % of whatever the earnings of all users. When you give me a bid, please state your crypto mining experience along with creating crypto wallets for users. You must also demonstrate your ability to secure the website from hackers accessing our users wallets. If you do not list your experience, your bid is considered non-responsive and will not be entertained.
