Attaching squeeze page to main real estate webpage

[Michael Norris]

I am working on creating a sellers squeeze page, but in the future it would be nice to attach the sellers page with a main real estate site. ( Ex. Mainsite.com/sell ) 

Is this possible to do ion the fly with out getting a programmer involved? 

What is the best practice, having up to three different pages, buyers, sellers and main site or just one site that is "forwarded" (I believe that is the correct verbiage) to both the buyers and sellers page?
