Oh please.... as far as BMW is concerned I'm guessing you'd also have to be certified to change the oil or replace a headlight bulb.
It's just a swaybar link, if the repair failed what's going to happen? It would be exactly like it was when she drove it into the shop. It's not like the sub-frame is going to fall off the uni-body.
I've got very limited experience with aluminum welding but I'll make 3 quick observations. Its much harder to control the weld-pool, aluminum weld-pools seem to have less surface tension than steel. Given the orientation of the car on the lift this could be an issue. Aluminum has to be really, really clean - much less tolerant of corrosion than steel welding and the heat input into the weld area is much higher, aluminum also transmits heat better than steel. Make sure there is no grease or oil anywhere near the weld area..... and make sure you've got a couple of fire extinguishers handy. You don't want a car on your lift on fire...... ya know the more I think about this the more I'm liking you're 'take it to a body shop idea'.
