If you flew me there I'd do it for free . It's not ridiculously hard per say... just the horrifying reaction of loved ones walking by many small pieces on the floor when you've taken it all apart. And actually it took me quite a few hours longer than 4 to complete...not to discourage you or anything.

I bet you can do it though - you'll need a few things:

1) Heat gun
2) Socket sizes (just get some to be handy - from 8mm to 17mm)
3) Black Epoxy, rubber sealant, etc.
4) A good DIY, though it gets self explanatory after a certain point
5) Could do hot glue (I went this route and it's been FINE in sunny CA weather for months now), or plastic clips

There are 4 bolts that hold the headlight housings in place.. then a bunch of disconnecting wires, then disassembly, melting the sealant to "ooze" and the simultaneous yanking of the headlight assembly (the part where you might want two people).
