I don't think it's wise to go that way. Agencies are closing left and right and that will continue to be the case. Design work is getting eaten up by streamlined tools that offer services to people who really only want any of a visual product, may it be a website or anything else, considering that you specialise in UI. The rest is taken over by freelancers. The market that remains has a need for high end speciality work that require dedication and attention over a longer period of time, considering that you use the marketing term "product designer", you should be familiar with that. It all depends on what you want to do, but it sounds like you are looking for a freelancer lifestyle, not an agency job. Before my recent job on a continuously integrated project, I did that type of work and I would never go back, ever again.
