Probably, yeah. And the way you're asking is probably wrong as well. Assuming your other posts are like the ones you've made here, you seem to be making a couple of critical assumptions about the people you're soliciting, among them:

1. They know who you are, or have any reason to care what you're looking for.

2. They don't already have somebody building their thing for them.

3. And if they don't, that they have any reason to think you're a qualified partner to work with

I mean, if I'm Joe Business Guy and you show up on a forum and make the statements you've made above, my first reaction is probably going to be "Who the fuck is this guy, and where does he get off making demands here when he has no credibility or reputation?"

I'd suggest a strategy of engaging with the communities you're soliciting among, get to know people, demonstrate value, probe gently to see what people are interested in working on, and then suggest working together when there are clear signs of a good match. Think of it kinda like dating. Imagine if you posted on a forum saying

"Hey, I'm Joe Random Anonymous Suitor and I'm looking for a wife with a demonstrated track record of good cooking, and a sizable dowry. Must be from a good family, and ready to marry and have kids." Do you think that would net a lot of responses? Yeah, it's just a metaphor, but think about it...

I agree that it seems I need to engage in communities more, and probably ones that are in-person

In my experience, typical business folks are too busy running their business to look beyond their everyday problems. I have lost count the number of times I have come across people using a spreadsheet program as a form of database, e.g. for keeping track of customers and email as a hierarchical filing systems, etc.

Perhaps you should read: "eMyth". The basic message is that most people are working "in" their business and not "on" their business. Which in turn means that only a tiny percentage of business owners would be even thinking about looking for some form of improvement.

Lest I sound too negative. My advice is to get up from the computer and go and talk to small business people, e.g. networking events, chambers of commerce, etc.

Perhaps you could try to be a more strategic. That is, at least get an idea of what your idea client / collaborator would be like. For example, if you are interested in health and fitness, then make contact with SMEs who have gyms, sports stores, provide boot camps, etc. Still on that same track, google to find some forums and directories and find out who might be interested in your area.

Ok, sport and fitness might not be your ideal, but the same principles apply to any general area. I firmly believe that you need to build up an interest in a specific domain/industry in order to find opportunities. The recommendation to scratch your own itch leads us to build stuff for other hackers/programmers and thus end up in a small and over-crowded market.
