it used to work well, but as of lately, google's been getting rid of alot of small-time affiliates. they particularly don't like clickbank products, and anyone that starts promoting them usually gets their account disabled within a few weeks. true story, it happened to me
Like was mentioned, Adwords + CB can go either way depending on a lot of different factors. Whether or not the product you're promoting is profitable from an affiliate standpoint is probably not validated this early, but there's definitely no harm in trying it yourself. It sounds like you are looking for more affiliates to pick up your offer. I might focus some attention on how to help affiliates sell your product better. Simple things are creating banners, other promotional materials etc. You could also try advertising a special affiliate rate for a select few people in exchange for them testing out your offer in a campaign. Whether or not you do it personally, someone needs to be the first to try it.
