Flash CMS for gallery area

I have a flash project that i need to add a CMS system to, I need a flash actionscript developer to build the gallery area and the cms backend based on my design requirements. The backend should ideally be in PHP or Xml although if its integrated in flash then this is no problem. There needs to be the ability to add and delete 1. gallery sections (these will appear in the navigation) 2. gallery content pages(these will consist of images which will be uploaded by the client and text fields) gallery areas will have an expandable amount of pages with them as set by the client and pages will be moved through by clicking a button to move across with a horizontal scroll. the text fields acssociated with each image will move down with a vertical scroll as the user clicks through. I need either someone who can recommend and change a template or develop this easily from scratch.
