Hello,

Building an exchange platform is not an easy task to do, especially when it comes to the security part, a lot of exchange has been hacked and people lost a lot of money. You have two options either work with a big team each with an expertise in a specific domain or with with a killing team of few people who are polyvalent in case you are interested in the second option drop us a PM and i will get back to you. Of course you need to define a budget for your project and also a deadline.

Good luck.
