Great decision. I also spend almost 2.5, 3 hours daily just to get to office, and back. Move closer to office is not what I want, but going freelance, just like you is what i want.
Great! It is quite different in the beginning, getting used to work at home and all. I recommend you have a nice space for work at home.
Good luck!
At home, i have one room just for myself, this is my working room and is temporary in the phase of renovation. I want this room to be great for working, nice and calm and without too many distractions.
My main concern are clients and how to find them. I have few clients now, but this is not too much job for now (which, on the other side is not bad because I have more time for my personal projects) and not too much money, which isn't that great :D.
