If they don't have to be EAB users, then I would highly recommend
Anthony Hoffman in New Zealand--excellent, meticulous work!
Granted, international shipping isn't cheap, but I can personally vouch for how key he was in repairing and recapping my A4000 and A3000 motherboards (even finding and repairing an audio issue on my A4000 that I wasn't aware of), as well as recapping my A3640 (including upgrading it to v3.2), and an A3630 recap.
He's pretty busy, but he does an amazing job, thoroughly checking and noting his work, and his prices are very reasonable for the level of expertise he has and work he puts in.
His website and contact info are below:
