What's holding potential customers back the most? The quality of the work, implying you are already exhausted after your current job? Or the fact that 20hrs is often not enough time for a meaningful contribution in a development team and you have to spend time to catch up every week?
Courious to know what your experience is and if a price conscious buyer would be willing to accept the trade-offs.
working with freelancers that have full time jobs almost always means that that freelance work is lower priority to their main job and will be first to be neglected if things get busy. Freelancers/consultants that do it full time value their good reputation to continue getting clients and work.
It’s all about communication and setting expectations. If client is expecting quick delivery with low chance of disruption and you have a full time job maybe this consultant shouldn’t take the job. Or at minimum tell client they are juggling multiple priorities at the moment and say that they’ve built in a buffer into the ETA but it could still be a risk. And that you’ll communicate frequently with any deviation to your ETA.
Not every client needs delivery at breakneck speed.
