I'm your man for the Job :)
I've just finished another website using a CMS I've written from scratch and from the ground up 100% mine, secured, fully O.O.P, with Anti-Piracy Techniques and can do more than what you need.
It's easy to be used, and has a good backend, and if you're interested just like how I did with my last employer, I won't ask for any milestone's payment, until the Job is done and you're satisfied, and trust what I'd rather look for rather than just money.
Get back to me if you're interested, and check your PM.
