With the different options of employment (freelance, agency, or full time work) at this point in my life for the sake of a more cohesive schedule I would first opt to try the full time work route with a company. I have worked for small design firms (in print production roles) for many years where I do not get health benefits and am underpaid, so looking for a company that provides fair pay with good health and PTO benefits is something I am more geared towards looking for. Freelance seems like a lot of foot work having to manage schedules, send contracts and invoices, doing quarterly taxes, and having to potentially deal with not being paid in a timely manner by clients. I believe agency work would be a back up plan if finding full time work on my own proved difficult, especially since the agencies I have reviewed build in a health benefit package for designers that work with them.
