Hi, I'm looking to find a developer, who can help me on the following website: [login to view URL] I need someone who can: 1 - Develop a "Gumtree style" ad listing for "BABY BUGGIES" and other "CHILD RELATED ITEMS", and ad searching functionality, to run on the above website. Happy to remove some of the content, in order to accomodate the ad listing functionality. The initial Functional Requirements are: (There's a lot of other dev that will be required in the future, but this is a start) 1 - Ability for user to post an ad with images 2 - This user will need to be a regitsered user, and therefore require a login in order to post an ad (DB requirement) 3 - Ability for users to update, remove an ad. 4- There needs to be an admin panel, and a user profile panel. 5 - Ability for a user to search for ads (fields to be discussed and agreed) 6 - Functionality (if possible to be integrtaed into: [login to view URL] can remove a few current features) 7 - A responsive development required. If and when this is succesfull, and we have developed a good working relationship, there will be additional bigger project to undertake: I.e. Developing an online store section on the site. Please repsond with a genunie Quote and timelines of when this can be completed.
