I'd recommend you to search for specialists who can provide you a very close bid. You may find local contractors or find them on Google.

Yet, if you want a recommendation, I might be of help somehow.

When I was building my ceiling, I used http://www.getproquotes.com alongside with other websites to get quotes. And their one was the best. So, I had chosen them. You may find more of this in their websites: http://www.getproquotes.com/prices-and-costs/ceiling-costs.php

Simply try getting a quote from them. Hopefully they can satisfy you. Feel free to contact me if you want to know more about them.
