Not that I know of, but I use Descript for content creation and it offers something like what you're describing. they have automatic speaker labels built in to their transcription service.
what i like to do is work with agencies for a limited trial period. i give them a couple of easy, medium, and hard tasks, and see how they fare. based on their performance, i hire them or move on to someone else.
This helps me test the hypothesis that this is the right group for the job.
That said, I don't know if that would have helped OP. It seemed like timing (End of year is always a slowdown due to holidays, and Feb-April are when other clients start ramping back up) was not on their side, but breaking things down into more bitesized work could have helped. Most of the work I saw was mockup/design work, which is more creative/subjective than your typical "Make button do X" kind of task.
Glad to see another company tackling this. I started a company (https://www.getairmed.com/) to help address this exact problem back in 2019.
I am a firm believer sleep apnea is under diagnosed and widespread. While I agree with the sentiment that CPAP isn't the panacea here, my CPAP machine changed my life for the better. Whether its a mouth appliance, CPAP, or a didgeridoo (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1360393/), I look forward to a world where more people can live better lives through healthy sleep.
I am on a m1 macbook air and I've been using Docker + Docker Desktop without much issue, and my use-case is a little simpler than yours (only running single containers at a time).
I'm genuinely curious to learn more about what these tools (Colima, podman) help enable. If I'm missing out on a performance boost, I'd definitely check them out.
