There is two things that Im looking into doing with

Hi,

There is two things that Im looking into doing with Marketpress. First of all, can I just use marketpress for on section of the site? I don't want to turn my entire site into a full fledge ecommerce site just yet. Only about 7-10 items for now. Would I be able to customize Marketpress for this?

Secondly, we are a rental company. I want to be able to calculate how many days a customer rents from us. Can I customize marketpress for something like this?

Thank you,
Virgil
