This is a good idea, especially for people like me who spent way too much time learning the ins and outs of making a server. I quickly learned that few people know all the important stuff.
I've had to basically do everything for my server because the only people I could find are builders.
I spent a lot of time making resource packs, configuring plugins, writing skript code, fixing bugs, and so many other things, I feel like I need to share or use my knowledge on something other than my own server.
I would be interested in this very much, lots of people would love this service.
And not to toot my own whistle, but I feel like no one can make a good Enjin site, mine looks beautiful heh. So even with an easy service like enjin, most people still need help.
I'm also really good at making custom Launchers with source code.
EDIT One last thing, I'm an excellent Skript writer, I could almost replace any plugin with Skript myself, and have even created things like a Jewelry API, and In-Inventory menu buttons that look and work beautifully.
