Hi Sami,

First of all, you have a beautiful looking theme and the integrations are perfect:)

Second, I have to second the notion that just building an awesome product isn't enough in the WP space these days. Marketing your product and business is a big part of the puzzle.

Of course, it's not easy if you're not the marketing type.

My advice (not that you're looking for it), would be to keep your options open for bringing a partner into your business, and one that compliments your skills by providing the parts of business that you're not interested in doing...marketing your products and shouting it from the rooftops;)

Case in point is how our plugin business came to be. I am the marketing type with a long history of WP. I tried to be a developer, a designer, etc. and it just wasn't my skill set, but I looked long and hard and somewhat by chance, found an awesome partner who was looking for someone with my skills. You can read about it in a bit more detail here:

Anyway, you're experiment seems like a good start and of course letting the community know via WP Tavern helps a bit too;)

I wish you the best of luck and don't hesitate to reach out if you ever want to chat WP business over a virtual beer:)
