Create an investment platform with sale and purchase of your own balance between users.

Hello, I am looking for a person who can create a platform with decentralized benefits. that in order to buy a membership, the user has to go to a balance buying and selling market and can buy balance from another user who sells, since they are going to withdraw their money from the sale. and you can choose the withdrawal method, by paypal or bank or cryptocurrency etc.. but that it be an exchange where I, the admin, is a mediator for both, and avoid scams. In addition, when registering, users must verify the page with KYC by sending their national identity document or passport or license. The page will have memberships where direct referrals are sold, which generate a daily percentage. I have more ideas but I want to be able to know who can do something like this? I need people who speak Spanish to be able to understand me better.
