Did you try Sitopway? $1 per board for 50 is a bit optimistic, but they might be able to do it.
2.7" is ~69mmThat'll put you in the <10cm x 10cm size, $120 for 50 to $190 to 100, so in the $2/board range.If you buy 300, can be at $1.25/board. Plus shipping.internationalcircuits.com could be another option, they get competitive at higher quantities, and will do ass'y also.At the 300 qty, US manufacturers might give you a good price too, try http://www.advancedcircuits.com/
