goddamn, three totally ambiguous posts!
@ericibe - if you want help you need to be more specific.
first of all do you need help with design, implementation or an ecommerce solution? no one will tell you how to do all three without some form of direction from you as to what you actually already know/dont know. but you need to break it down into at least a site design. choose a suitable cms to implement the ecommerce store. then you need to build up the database, link with paypal/3rd party merchants etc. there are many, many steps, and its best to tackle them in small components. my guess is that you havent started. first of all I would suggest to you to do some research on CMS' that can handle e-commerce. once you've found one that you like. then research how it works. if you do not know html, css or php then learn that too.
once you've got that done then you'll need to start coming up with a design.
I'll see you back here in a few weeks when you get to that stage
@jaywebdev - either help people on this forum or **** off. I'm sick of people coming here just to get business and not help anyone, thats bullshit and against the whole point of this site. if you want some work, post it in the appropriate section. the OP asked for help, not for you to sell him shit, if you aint gonna help then dont bother posting.
@noelagnote - damn straight!
