What are you offering?

To get the server, domain, make the configuration and let the client run the casino?

Only the source code and let the client install it and run it?

Does your casino have it's own games or those are some third party games?

What about the deposit and withdrawal engine? does your casino software run it's own node?

I hope you can answer all these questions to have a clear idea about what you are offering, depends on your answers if i buy your service or not.
