Front end user product input

Hi,
Iv made a website for a client and want to add a link on the front end sot hey can add their own products, it would be easier if on this page they could confirm the order and it becomes active as they hit submit.
Can some one please help me work this out, iv looked in the posts but cant find a answer.
thanks

Hello,

It's not possible for the moment . We're working on a multi vendor system which would allow you to have something similar but it won't be ready before at least september.
