Electronics Technician Wanted-UPS repair (Broomall)

I have some APC UPS Backup power supplies that need some circuit board troubleshooting.
I have some basic electronics knowledge but could really use some help from someone who has more experience than me :-) In exchange you can have some of the units we fix.
For example I have two 3U rack-mounted APC SU3000RM3U units.
These are beasts! Also some smaller SmartUPS and BackUPS units.
I think all we'll need is a soldering iron, multi-meter, O-scope and some small caps to get these back up and running.
Can you help?
