I had 2 DUI's about 6 years ago, is it realistic for me to become a commercial pilot?

I had 2 Dui's (one when I was 21 and one when I was 22) and I'm now
almost 28. I was working on a degree in communications and I'm at
about the junior level, but my old dream of flying just came back to
me all of the sudden and I thought I would make absolutely sure if
those DUI's will be more than just an obstacle for me.

Where I am at now is just trying to figure out how I can be sure one
way or another. How do I get the official thumbs up or down? I can't
bring myself to invest all that money only to be unsure and have to
wait until I get further down the road and committed to find out.

A teacher at the community college I go to now said he wasn't sure
about 2 dui's but he's seen people overcome one. He also gave me the
website www.jet-jobs.com for Air Inc, and said they can advise me and
they charge for their services. I thought I'd exhaust all my options
and ask here first/as well.

Any help, advice, or experience is really appreciated. Feel free to
email me!
Thanks,
Jarrod
