Mike, the very best, tried and true, effective method to reach small business owners is to give them something. Example: Search out small business owners that interest you. Invite them to do an interview with you.
The question is what's in it for them to take an hour out of their day to talk to you?
What is the benefit to them?
1) Record the interview - give them the recording.
2) Transcribe the recording - give them the transcript.
Both you and the Business Owner can use the results. Promise and keep your word to use the result in the most professional way. Blog about their business, what you learned from the interview. Recommend them and their business. Tweet about them. Send an audience to them. Set yourself up as a go-to resource.
Two things occur with this method.
1) You build a credible reputation.
2) You build content.
3) You then have more to blog about.
It is all about the give in order to receive.
Give it a try.
Hope this helps.
