I need someone who is very experienced with zen cart and can do customizations quickly. I want to extend the functions of my check out pages by offering unique upsell options based on product id's. I also want the ability to create a variety of subscription packages and payment plans for my users. System currently works well but want more flexibility and control in admin to setup my plans and upsells.
For example, if a user buys product 1, i'd like to be able to offer that user a special offer or donation option based on product 1. Perhaps it pops up a lightbox with "no thanks" option of it can be embedded in checkout as "check out this exciting offer".
Any samples would be great.
experience with jquery is a plus
