I was in the same situation as you. I was 33 and ready for a career change. I did my private part 61 at a mom and pop flight school while I was still working and I only flew a day a week and it took me about a year to get it done. I then quit work and went to flight school full time and went to a 141 school that had a professional pilot program. I went through instrument, commercial and cfi in just under a year and started working at that school. I would say if you can swing it go to a 141 approved school that has a professional pilot program and get it done so you can start working and building the time. I committed myself to it like a full time job and flew 5 days a week plus spent ample studying after flights. If you are able to relocate for a flight school that really opens up your options. One thing to keep in mind about the accelerated programs is that time they show on the website is dependent on a lot of variables. Shop around and make sure you find a school that is a good value for your dollar. You will be spending a lot of time and money with them so you want to make sure it is going to be a good fit. If you have any other questions feel free to pm me.
