I am looking to implement a new, highly customizable shopping cart for a few ecommerce websites. We are currently using a 3rd party one we link into that is erratic, inflexible on the design, and difficult to make changes on in a timely manner. It is preferred to work with one that is PHP / MySQL based.
The following are the requirements we are looking to meet
o Convert .psd layouts we produce into shopping cart and web page templates or themes

o Ability to use our collection of zip codes to provide different shipping and delivery costs as well as different shipping and delivery options to customers based on specifications we set for that particular product

o Support available

o Use CSV files to add / remove / change quantity / change stock / change product specifications

o Emailing of order confirmation, tracking confirmation

o Possibility of working off of a database we would create

The ability to customize the look and feel and adding functionality like the zip check is crucial. I am only familiar with so many of the shopping cart software and am open to the possibility of bringing in programmers to develop our own or do work on an existing one

Is this a job post? Are you offering a payment? Or do you want suggestions on how to build this or where to find something like it?

No im looking for insight and opinions on what proficient programmers feel the best, most flexible Shopping Cart platform to work off of is if the better alternative isn't somehow constructing one from scratch

Building one from scratch is of course the most flexible option, but it's also likely the most expensive one. - At least, if you want a decent one.

Though, I doubt you won't be able to find an existing solution you can't customize to your liking. There is no shortage of both commercial and free eCommerce software out there. I'd start with the open-source software. At least with those, you have a starting point; you won't have to build one entirely from scratch.

We use this one, http://www.gettrolleyed.co.uk/

It's our own we develop in house so I'm bound to be a bit biased. It's written in perl and the html templating is really flexible as we just use perl's mega brilliant regex engine and template tags like #title# and <!--content_wrapper-->(.*)<!--/content_wrapper--> meaning you can write your front end however you want.

GoCart is a good solution too, based on the CodeIgniter framework.
