The number of times I've created a Minecraft server is absurd. Your details are a bit vague, but I can guarantee I can create you whatever you want (granted it is within the price range). I'm very familiar with the MC API, as well as being a certified network engineer on top of working towards my Master's degree in computer programming. If you could please get in contact with me regarding the details of your server, I'd be happy to start work right away!
