Er... You're going about this the absolute hardest way possible.

Instead, consider this.

There are 2-3 WordCamps running every month somewhere in the world.

There are currently several 100s of WordPress related Meetup groups with between 1,000-10,000 Members.

There are 1000s of other technology Meetup groups of similar size.

There are 100s of daily conferences, expos, Co Work office continuing education sessions.

Don't hire out your marketing.

You know your product better than anyone else.

Just start speaking at groups about your product. If it's good you'll get rich.

If you're comfortable speaking to groups, this is likely a minus as you'll seem to polished for techies.

If you're completely uncomfortable speaking to groups, you'll likely get rich.

Rarely will I pitch myself for a phone call...

And in this situation, I've made my money primarily of WordPress related projects for years. I started using WordPress back when it was B2 (pre WordPress name change).

Also, most of the people I work with daily generate most of their income from WordPress related work.

If you get stumped, book an hour call with me (it will take that long) to map out an end-to-end marketing strategy for you to hit your income targets, via purely solo activities...

So you keep 100% of your money.

And you skip 100% of the aggravation working with other people.
