My experience actively freelancing is dated now but I might still have some insight you would want to hear.

1. don’t expect to make good money right off, in fact expect too pickup a part time job to get by. it takes years to build a client base that is capable is supporting you unless you’re skills are highly sought after.

2. when I had a similar skill set I found local job boards (Craigslist, Reddit/Lemmy, etc) much easier to get work. The clients tend to be easier to work with as well because they probably won’t have the same expectations on a large freelancing site.

3. managing client expectations is the key to success, know you ability and spec jobs for longer than you think. It’s better to get passed on a job than stuck with something you can’t do.

4. this might just be me but the business side of things is a drag and takes a lot of time. Marketing, specing, client relations, it was too much for me as a one man shop, don’t discount how much time it takes.

Good luck out there, freelancing was the hardest but also most rewarding work I’ve ever done. You’ll be forced to learn a lot in and out of tech at a breakneck pace. Some of the best lessons I learned have nothing to do with 1’s and 0’s.
