Face to face may be great but it isn't as scalable as the online landscape.
A solid inbound marketing strategy will bring leverage and do most of the initial education that you are spending a LOT of time doing yourself.

If you are doing a fair amount of online marketing, I'd assume you are building an email list. If you're just talking to inividual people online, you're still just doing "face to face" activities .

You can be educating multiple people in multiple places using multiple platforms with a ton of automation to do the heavy lifting.

From there, inexpensive advertising will be a great tool to attract more people to your funnel.
