Hi,
I'm trying to customize Zen-Cart with a completely different layout. I'd really appreciate some guidance or advise in how to get my way through all the process.

These are the design mock-ups i've already done, as you can see will be totally different from the standard zen-cart website...

Any of you has gone through a heavy customization like this?

Mostly: Can it be accomplished in Zen-Cart?

I'd really appreciate some advice in the methology and how to get started, I'm new into shooping cart packages and completely lost at the moment.

Thanks in advance
