1) support isn't scalable, but if you're looking to pull yourself out of stagnation, then you shouldn't discount options just because they won't scale well.

2) this is the option that scales the best. how long ago did you look at the numbers? hosting something like this is quite cheap, and this is the option that gives you the most possibilities to monetize with multiple levels of plans.

3) sounds like a management issue to me, not an issue with the concept

edit: i've worked with jobberbase and submitted fixes to it in the past, and i've worked with other job board software. i've seen people drop thousands of dollars on terrible, outdated job board software without even having a full license or support. you have a market if you can just reach it. jobberbase isn't easy to find unless you go digging and know what you're looking for. most people who are looking to host a new job board do not know what they're looking for.
