Please post your list of equipment here and the types of interfacing you would need as this would help us try and determine the level of effort in hours and then break it down by cost/hour.
For example,
Denon AVRxxxx - RS232 via RFX9600 or Denon AVRxxxx - TCP/IP (Telnet Port 22) or Denon AVRxxxx - IR via RFX9600/RFX9400/Line of Sight
Sony BDP-N460 - IR via RFX9400 Extender Mitsubishi WD65835 - IR via RFX9600 Extender DirectTV - IR via line of site.
Then for Watch type of activities, you have Watch Blu Ray Watch DirecTV Watch Cable TV Watch Blu Ray with surround Watch DirecTV with surround Watch Cable TV with surround
Then same for types of listen activities.
And finally, if you are trying to do any type of home automation such as HomeSeer, Lutron, or any other things, also helpful to highlight those here too.
The level of effort required depends completely on the type of interface connectivity you desire as well as the interactions between components.
For example, you want to Watch Blu Ray. That involves controlling a display/projector, the BD player, and possibly if you want surround sound, an AV receiver. The Activity in the Pronto will require connectivity and monitoring possibly for all 3 pieces of equipment.
With more information, you may get more responses as I'm sure you don't want to write a blank check and anyone doing the work would want to also ensure they bill for appropriate hours, etc... A contract of sorts.
