On suggestion from Grant M, I sourced motors from a website called www.banggood.com, or more specifically http://www.banggood.com/Wholesale-Motor-c-3792.html

For the extending jib, im using a T8 300mm Stainless Steel Lead Screw Set with Shaft Coupling and Mounted Ball Bearing 
And a range of DC12V 100,150 & 300RPM motors roughly $6 each.
