I accomplished what you are considering; and you might look at another avenue.
I went through a certified school at a local technical college for eighteen months and the cost was about half of that quoted in an earlier thread. The requirement as far as the FAA is concerned is a minimum number of hours of training and some of the schools will work with you on a schedule that will enable you to modify attendance or classes to reach that goal. Check with some technical schools and see if they offer night classes, weekend classes, or other options that might fit into an acceptable schedule.
