Look into embry riddle. The cost is reasonable. You can do it all online or take some classes in person, on a normal 121 reserve schedule I had no problem taking one course per term. With more than 10 days off a month you could take more. I am on my final capstone course and should be done this spring. In total about 3 years, but I did take a few terms off for financial reasons and for training when I got hired at my airline. Good luck, there are a lot of online options out there now.
