Hello.
I've done a couple of similar projects in the past, both using PHP. One in particular was a simple web tool to gather data from various RSS feeds according to certain rules (primarily text matching) and place them in a resulting XML file.
Since you require the rights on the project, I'd create it from scratch following your specs, but I'm confident it could be completed in 8 days.
Perhaps the most important issue to discuss in detail is that of the available resources, since you say it needs to run in a script safe_mode installation of PHP, so care needs to be taken to use the proper extensions and so on, but eventually there shouldn't be a problem.
Thanks.
