I would own a free-of-charge website (but I'm here to pay you to develop it, of course), preferably in PHP+cURL (second pref.: ASP .Net) where service buyers like me can submit their project once for having it automatically published on all the 10 biggest freelancers sites like [url removed, login to view], [url removed, login to view], and so on..
In other words I need a site for posting projects on 10 freelancer's marketplaces at once, in a single action.
*I* will give you the list of these 10 biggest sites, that I already selected.
This website will be hosted and owned exclusively by me, and you (the author) will only keep, if you want, unlimited free-of-charge use of it like others, for life.
The GUI must be well designed and the engine must be well coded and visually ordered, with comments and a full error handling.
I'm open to pay you more than your bid if I see that you do an excellent job or you are particularly fast and flexible, and to pay you for future improvements of this website.
I would like to have a long term business relationship with you.
Payment: I escrow 2/3 of the payment immediately after I award you and you accept and will complete it at its fullest when finished.
