I seriously think a free sampler would be perfect.
I know you love the game and you have played it a few times, but that is one person's opinion and that person is a friend who sees him regularly. I'm sure that doesn't affect your judgement, but it would be nice to have an 'outside' judgement.
Perhaps send a copy to 'The Ancible' magazine to be reviewed (perhaps even the SSFFW) and put a sampler online. Getting a sculptor is a different matter and expensive. I understand it is a home business and getting sculpts done is expensive business. But I don't think it's necessary. You juyst have to be smart with how to sell rules.
