Thanks! Well actually the concern here is that I have been away from academics for a good 10 years. So I do not really know if my professors from my Grad school would even remember.

I think you should try to get in contact with them, check your chances with each professor, show them what you have been doing, talk about your plans, seek guidance, refresh their memories. In short, get close to them again. If you just show up after 10 years it will really be strange.
And being way from school for too long is also something to worry about your application. During my interview, a professor said that age is not a problem, but older applicants may be a little rusty in their academic skills. He said that I was ok because I just finished my Masters with great results, that was some proof I was still academically sharp.
