Crypto Payment Gateway

Hi, I'm looking for a developer that could create a crypto payment gateway system. The shop merchant can integrate my system into their website. All of their customers registered on their website can make payments with crypto either with erc20 or trc20. All of the merchant customer will receive eth trc20 address or eth erc20 uniquely for them to deposit. Once the user deposits into their unique address, the shop merchant can withdraw all of the customer amounts all at once.
