Hallo Syan,
This is a nice ('bid_crawler') project and I'm more then able to create a good and userfriendly package for it, also for your future (and maybe yet not known) websites.
There will be no software updates needed when adding new websites, or when their characteristics changes!
At the moment I'm directly available so it can be solved on short notice.
Regards,
Ruud de Ruiter
