I think I speak on behalf of anyone who would want to do this. You may want some kind of contract deal. If you are super serious about doing a great server, I have just a few suggestions.
Don't make a minecraft server, just to make money. Its against the EULA, and it will turn players off, use them to make donations and don't restrict items via ranks. (against law).
If your really serious about doing it, you should really start making your own plugins, etc as one of the things players love are custom plugins. It makes your server more unique and fun!
Hire a team of builders (if your really serious) and build a good server spawn. First impressions are everything. This can run you 3 to 5 hundred dollars to get a really good spawn.
Start small, grow a small player base. I can never emphasis this enough. If you try to go big in the first few months you will fail miserably. Grow your player base, slowly and surely.
Most networks, started off being a small factions / creative server, so if you notice this pattern stick with it!
Get a good team of staff, do not hire randomly people. When players start to join your network look out for really helpful and kind players. That would make very good staff.
Treat your staff well, make sure they get to have fun too. They will work harder and overall increase the Moral of the server. Really make sure you do this!!!
Use good ethic's, listen to what players want and really try your best to bring a unique, simple, and amazing area for people to play.
