Cryptocurrency withdrawal/deposit system for online casino

I am looking for an expert to design and develop a cryptocurrency withdrawal/deposit system for an online casino. The system should be able to support the deposit and withdrawal of Bitcoin and should also be able to handle high transaction volumes. Additionally, the system should have the capability to support fiat (real world) deposits and withdrawals, although this is not a requirement. The timeline for the project needs to be reasonable and the price should reflect the quality of work. If you are confident that you can deliver on this project, then I invite you to submit your proposal. Thanks in advance.
