we want a delevoper who knows drupal a lot. What we want is a platform that people would register and so after registration they could install drupal from their profile with the appropriate sub domain . all set up of the drupal like username and pass for mysql should be done automatically without the need of the user to enter them. now all products that users will upload on their drupal sub-sites should be diplayed on the main market web site.. and if any selling is done then this would be charged with a percentance of selling price . this percentage will be controlled from admin for all users from people section ( drupal 7). the selling will be achieved only on users sub websites..(from their subdomains) the main web site will remain as a display for the rest sub domain web sites. when they will choose to install drupal from their profile . there should be an option for preintstalled profiles . commerce kickstart normal web site.. with preinstalled themes. and a few more. the project need to be finished yestarday. so please only serious developers . drupal module developent is essential as portofolio. in a few words .. what we have is drupal , commercel kickstart, sub domain modules, what we want is a module in the user profile that he can install a drupla web site with one click.. all other mysql , etc should be done automatically. then .each content type (according to profile would displaed ) in one of our web pages ( this could be created by views) thank you for your cooperation.
