If you think running a bitcoin exchange is just buying some pre-written code and running it on a server, you're totally wrong. It's going to take a lot of work, a lot of connections, and A LOT OF MONEY assuming you actually want an exchange that works decently and is secure. You're going to barely reach anywhere with just spending $10,000.
Take a look at the previously hacked exchanges. They couldn't even protect themselves even with all their earnings. What makes you think you will be able to do well?
Anyway, I'm not here to bring you down, but just for you to be more realistic here.
If he wants to run the exchange as legit as possible, securing licenses is one of the initial steps that he needs to embark on. And there's a lot more in it not just buying the code. I hope the OP realized what it needs to run a legit and decent exchange. Even after setting this up, there are a lot of things to do. Or if he wants to run a substandard exchange without any existing license under it, maybe he can. But in the long run, traders will not trust this exchange and so it will just bite the dust of crypto.
