Hello, We are looking for a developer to help us complete our site. We have created the site on yii framework but its full of bugs and issues. We want someone to fix all issues and rebuild the whole site, features and fuctionalities to a more stable platform (for example magento, open cart, wordpress etc..), bug free. You can see the frontend at [login to view URL] . user/pass: admin/admin admin backend is at: [login to view URL] . user/pass: admin/admin Because we were victims of freelancer scams for 3 times already... This time we will not created partial milestones. We will create only 1 milestone (or 2) and we will release it only uppon completion and full (100%) satisfaction. You can work on local host until payment is released if that can make you feel better.

A user can create a profile and then he can do whatever he wants in the above areas.. Everything is connected together. We have featured, bordered, top listed enhancements for profiles, for ads and for products... similar to souq.com. Pls take your time and check the website's features and issues before bidding in the above link. You will have to complete all features and functions in the new platform, even features or functions that are currently not working on the current website. Also we will probably make some changes or additions. The website will be build in 2 main languages Greek and English. We will provide Greek translations We will also have a google translation option but will be disabled for start. Some features you may not have see are: We have a popup window at first visit , with some banners(we have an option for activating the pop up in admin backend). A profile's url should be at [login to view URL] or [login to view URL] , domain.com//"username" . For news section we would like to be able to get feeds from here : [login to view URL] . And at news section we want an option to add manually a new post.. Automatic email notifications.. and ability to change them during and after registration. A function/option to send daily or weekly email notifications (throught admin backend).. with selected products or posts from all areas.. i mean we must have a template.. in which we can add products from shopping area, special offers area, services area, classified ads area.. etc.. all in one template (few from each category) and send it to all newsletter members.. when a user register the newsletter email notifications must be preclicked. Last we will need you to create for us some banners (ads)... For the popup window and for some other areas.. And some banners for our page promotion in facebook (posts, timeline covers). In your bid write clearly which platform you recommend and time estimations. If you have any questions we can discuss them in chat. Our final budget will be decided later when we receive all bids. Attached you will find some files which includes some of the issues found during testing on the current website. The awarded developer will work with us in a long term/ regular basis. Pls do not bid if you don't accept our payment terms. You will get paid only if we are 100% satisfied with the project (website). If the tasks are not done 100% the way we want them and if we are not 100% satisfied with the result we will not release any payment and we will claim full refund (and we must accept it) for all milestones.
