Hi!
All questions would have been pertinent to the new database schema on teh CRM side, but you said that would be unavailable at this time, at least not for everybody bidding.
In any event, I don't think it would require more than couple hours - to get familiar with those database functions in [login to view URL] and [login to view URL], just to make sure not to break anything, and with the new schema and what you'd be wanting pulled from there(you said teh output would change too), and to plan and do the actual modding. And then the 3rd hour is for testing and debugging/problem rectifying etc. on the modded code(because we don't have neither side of this communication and data to test locally, and it's not even worthed to set it up locally only so it can be tested anyway.
Kind Regards,
Dobri
