You don't need anyone to be in the state to help with building dotnetnuke websites, let alone the country.  I've currently worked with a large company  Calibre Global in developing their intranet - I'm not sure but I may be going over there to assist in training for a few days when the sites are commissioned, there are 4 portals that are involved in this intranet. 

I know that http://www.multiskilled.net do DotNetNuke work since they manage the transwa and new metrorail websites, but I'm not sure if they are primarily high end developers and not in the space of training but more project management and doing the jobs themselves.. but they've been involved with DNN since DNN 1 days.

Are you after having developers trained? Isn't that more a project specific task? 

I agree with your approach, in the last several months I'm working quite closely with companies who are either new to DNN or rolling out their second/third portals and want to get the management of it right - there is a right way and a hard way to work with DNN when it comes to long term mangement.

Anyway - you might like to contact multiskilled - John May is the guy in the know there.
