Affiliates do not link directly to your domain though, they tend to be just redirected to your site so they are useless with SEO.

True, you will only get direct hits from users, but some search engines do pick up the redirect and follow it your site, not google though.

A good way to get backlinks sometimes is to just ask, you will be surprised that some are willing to do you the favor.

Best way to look for it is to do an exchange with someone interested in the same thing.
