We have a free online course to educate prospects, but are a bootstrap startup with no awareness, social proof, or web traffic. Can't find Reddit or Facebook groups with the right target members. Our managed service creates and hosts custom solutions using our process and tools, priced from $10k.
Be helpful.
Seriously, go find where those consultants and service professionals are hanging out (Clarity.fm, LinkedIn, their own blogs, their Twitter/Facebook pages, forums, MosaicHub) and help them. Consultants have questions about whatever you're pitching.
Start be delivering exceptional value. Their natural intrigue will lead them to your product.
I'm happy to help with a more detailed plan if we can discuss who you are trying to target. At first blush, it appears your audience does not exist or you are not hunting hard enough. :)
