I don't lack professionalism because I'm unable/unwilling to provide the same level of support that full time specialists/shops offer. I'm just not a fit for jobs where that's what needed. Maybe that makes me less of a specialist, but it doesn't make me inherently unprofessional. And a lot of times that's not what's needed! As an artist I'll tell you that in art worlds there are plenty of professional jobs where you do something well and walk away... There are others who are better suited to taking what you've built and integrating it over a longer term, particularly, it's people who have stake in the project.

Have you ever done freelance web stuff for small businesses? There are some people who want you to be their webmaster... You give them a CMS and they want you to go fix their typos. So you say "Okay, sure, but it'll be $50/hr" and then they get frustrated because they don't have someone doing that kind of work on their end. They think it's your job to "make their website", but don't want to take ownership of the thing.

This is an analogy for the kind of thing I'm taking about. I want to help solve problems, and I want to provide value for my employers, but I'm unwilling mindlessly give up my time to people who don't value it outside of their myopic needs. A lot of times, that's what's expected to be "a professional". Well I don't want that. I'd rather be an amateur who's also a respectful and savvy business partner, who's definitely interested in helping you with your project but also keeps healthy boundaries for myself.

I'm definitely more of "an amateur" (lover of) than a professional, but I don't see why that should make me automatically "unprofessional" in my business relationships. On the contrary, I think it's fully possible to "be professional" without providing unrelenting 40+ hr/week service for a year. If that's not what you're looking for then with all due respect that's fine! But please don't blanket assume I'm "less professional".
