Need Flex/AS expert for Snackr modification & optimization

Hello bidders, We're using a modified version of Snackr as one of our widgets. It's modified to display data parsed from a php script outputting RSS2 data in simulated real-time. I'm attaching a piece of code which is designed to choose and pick items from the RSS feed. This function is heavily tasking the CPU and causing the application to crash. We need this function optimized. See attached file. It's an AS3 function. pickType != PICK_TYPE_RANDOM_BY_FEED You must be very experienced in Action Script and be very familiar with Snackr. If you have any questions, please use PM. Thanks, Sam..
