Flash slideshow backend setup

I have been given the responsibility to add a slideshow to the home page of a flash website that already has a gallery setup with slide show capabilities but they appear on the gallery page. I want a slide show similar to the ones in the gallery to show up on the home page and be managed using the admin features already set in place. I wasn't able to figure out how to use the already in place system so I just hacked the flash file to display a rotation of images fading in and out to simulate the client's needs temporarily. We just need to hook it up to the back end. I'm sure it would be easiest for someone who could understand the flash file. Looking to spend no more than $30 for this flash file modification. The website is devphotovideo.com. I created the homepage slide show, which I need to duplicate using the same slide show front/back end that is used in the gallery page. The site admin clicks the admin link at the bottom to add images to particular galleries. The home page slide show will not need any of the navigation links other than play and pause just as on 'gallery' page. I'll need the modified .fla file.
