It looks like you are looking for a prominent member on the forum to advertise a project under development. Please open a special thread on the Services board to make it easier for you to find the user that suits your needs. Some of the users mentioned in the topic are prominent members on the forum, you can directly contact one or more of them to negotiate with them.
Considering launching a Campaign can broaden the introduction of your project to forum members, you can manage it yourself or choose a reliable Manager, I recommend Hhampuz if you need his services.
