The fastest way is to use leverage. Leverage technology to sell digital copies of something you only have to make once (which you seem to have already been doing and look to be doing more of.) Leverage time by hiring other people. Leverage money, which allows you to scale the other inputs more quickly than you would by bootstrapping. Preferably you would be able to use other people's money. In another comment, you mentioned that you aren't living in a developed country. It's difficult for anyone to get investment money and it may be more difficult where you live. On the other hand, you have access to relatively cheap labor. If you are able find decently skilled developers in your area, then perhaps you could apply what you are making on your WP product which is selling well and hire a couple of developers. You could also try setting those developers on jobs from Elance and Odesk. Maybe start out with a niche and build a brand for that niche. For example, build a WP team and focus on WP jobs. Too many developers on these platforms are too general. If your add-on is well known then that would give you a leg up on the competition. Actually, every add-on you create would add to your brand. Another crucial point is to find someone who can sell! Too many job proposals on Odesk and Elance are the types which start out as Dear sir, broken English and no demonstrable understanding of the item they are writing the proposal on. Get this right and you could crush it. Maybe even get someone from the U.S. to work on commission and pair that person up with your best developer (or yourself) to work on each proposal. Essentially the salesperson would dress up the proposal from the tech guy and add some spice. I'm currently living in the Philippines. I have been pondering going this route myself.
