I'll second what JAFO says about the VP2.
6'2" is quite possible for a VP if the builder was tall. I had to bring back the rudder pedals in my old one as I'm short and the builder was 6'+. It is definately a single seater for you, though for short arses like me, 1+ child is possible. Great fun and about as cheap as you get, so don't rule it out if finances are tight. Hand on heart though ... look for something better!
Pietenpol Aircamper is also probably a bit small as well, esp if your brother is of similar size to you. I think as others have said, the Champ is a good choice as most of the capable homebuilds will probably cost more anyway. The only real exception is a Jodel which I'm surprised hasn't been mentioned. A D112 or similar would easily fit the bill for somewhere between £10k (if you're lucky) and £15k.
