WTD Wheels (long shot)

Right, i know this might be a long shot on what is a main road bike/racing forum but as this is the only cycle forum i use i thought i may aswell ask

I'm looking for 2 20 inch BMX wheels (prefer 48 spoke and have at least a 14mm axle)

Starting a winter project that was supposed be done over the winter, but as i was busy i couldn't get it started, so its now a winter project being done through summer because i'm unemployed at the moment

If you dont have the wheels, but know a place to source them cheaply, any links would be great. They are to be the front wheels of my recumbent tadpole trike, so the do need to be strong hubs and preferably 48 spoke for added strength
