So you wanna resell him? Realistically, you might have a hard time getting $400, though--they really are worth more as a pair.

If you breed him to a non-het girl, you'll get 50% hets. I'd recommend upping the ante by getting him a nice MATURE pastel girlfriend. Or pinstripe or spider--then you have pastel/pinstripe/whatever 50% het for lavender. That makes the possible hets much more attractive.
