Alter a PHP Symphony based site

We are a top web development company located in Asia working. As a development company we handle all aspects of the SDLC, but due to the amount of work we receive we can offer some project opportunities to highly skilled developers outside our organization to work with us on. Project management, testing and deployment is always handled by us exclusively, so in your quotation please only account for code development. If you prove yourself to us on a project we will have many more to offer you on a continual basis. The following modifications will need to be made to a template that controls multiple websites. The updates are as follows: - Option to add Youtube video in the 300 x 250 banner section on home page. - In each category where the adverts/businesses are listed add a maximum of 6 adverts showing on the page with pagination for additional adverts. Currently template only supports a maximum of 6. - Change CMS for listing of adverts/businesses to accept coding for banners, affiliate links etc. More details to be given to interested and qualified candidates.
