Breanden Beneschott COO at Toptal . If you're looking for really great developers and designers, Toptal is the best example I’ve found at sourcing elite talent for companies quickly (they have a really thorough 4 step screening process).

If you want a warm introduction, email and I’ll introduce you to my good friend on the inside. He’ll give you the VIP treatment and you’ll also get up to a two week trial period for the Developer / Designer to prove to you exceptional work.
