Are you looking for those people that you'll hire or you just want someone to contribute and help you out sort things with your trading platform project?
Anyway would give some qualifications on what are the qualities that you are looking for devs and consultant.
Do you already have an idea what the concept will be like?
I guess they already have it and that's the concept as the title indicates on what they are really plan to make. To compete with other crypto trading platforms.
