development quotes

I am a perl programmer that has been given the task of setting up an  
online store with an affiliate system.  At the core I'd like to use  
Interchange, I think quite highly of it.  I've setup a store but need  
help to customize it.  There are to be 200+ products in 12  
categories, a refer-a-friend program with benefits, recurring orders,  
and a few other things.

Please contact me ASAP if interested.

Thanks!

Ryan Perry
