(Disclaimer: I work for Bizo)

Bizo allows you to target on specific business demographics (Company Size, Job Function, etc.), and to do so cheaply (starts at $5/day). One advantage Bizo has over Facebook, StumbleUpon, etc. is that the ads are shown across many websites instead of just one.

Unfortunately, "professional coach" is not one of Bizo's targetable segments, so other offerings may work better for CoachFire. Your other sites, however, may be a better fit:

LinkedIn has a similar offering (https://www.linkedin.com/directads/) that allows you to target people in the "Professional Training and Coaching" industry, but, similar to the other sites you mentioned, ads will only be shown to users browsing LinkedIn.

Thanks for pointing at LinkedIn DirectAds, I will give it a try and update my blog post.

I will also check out Bizo. Does it allow for small budgets as well? (like 5$ or 10$ a day)

EDIT: Answer to my own question: Self Serve allows $5 up to $300 per day.

I manage the SEM campaigns for Vistage (business coaching) at a digital agency. Looks like Bizo might be a good fit for them. Anyone in particular I should talk with to get some more info?
