This resonates with me, and I am sure a whole lot of other engineers working on side projects out here.
What's the solution? How do you find a "Marketing" person on a side-hustle budget? Without any network.
Like OP, I know my side-projects need to be marketed, but I also don't enjoy cold emailing or cold-calling and would really leave it to an expert in that domain, as long as I can pay him/her by output and not on a full-time salary or a contractor rate...
