Is there a standard for implementing our IDX systems to the websites?

Does that count against our 5 hours of programming time we receive with our templates?

Will we be able to "tweak" the system to add a (for example) Search Luxery Home button that would pull only homes over a certain value or a link that would do a pre-determined search for all of our office's listings?

I am trying to figure out how versatile the system will be and how much so on my end vs. having to have a programmer do it.

Thanks for your time.
