online dating

I have always struggled with girls mostly because of my lack of self confidence, but with in the last year or so it has been coming more and more natural for me. problem is I took a year off between high school and college to work. I work 6 days a week 7am to about 5pm which doesn't leave much time to put myself out there. i have been trying to try new things, during my job but my encounters with people are so brief that it is quite hard to develop any sort of anything with girls i talk to. and to make matters work because of my line of work the girls i encounter are generally married. I really want to become more comfortable with myself and refine my skills by the time i leave for school but it is looking to be quite hard if not undo-able. i have always viewed online dating as a last resort, act of desperation, and always sort of avoided that at all costs but at this point really seems like the only option to encounter single women on a regular basis. what do you guys think of my situation, any comments or advice is a big help.
