Thats a pretty expensive remote.... You might be served really well with the extreme flexibility of the Pronto - TSU 9600, for far less money...
Is this to be a DIY type scenario, or a custom company to do for you.....
But none the less... you will find far more support on a dedicated Remote Forum like Remotecentral.com
http://www.remotecentral.com
Do check out the Pronto... its amazing for the price...
I found the Pronto Very easy to learn, and the forum will help you greatly if you wanted to DIY, as the Software is free.
Even the owner of that site runs the Pronto....
I would imagine there are plenty of people that would program it for you for the price of the remote and programming for far less then what they want for the RTI
