Skynet is the cheapest courier I have found, very reliable and just as fast as the big names.
www.skynetworldwide.net
10kg to the US will cost AED 465.00 this compares very favorably with the postal service which does not provide a courier pick up and delivery.
Empost will cost AED 941.00
ETA Just noticed you said pounds not kilos, 10 pounds would be AED 315.00 with Skynet and AED 521.00 with Empost
