A lot of firms are starting to require a 4 year degree, which limits you. With that said though, your sales experience should help you get your foot in the door.
It's not an easy business to get into in the first place. If I were you I wouldn't be worring about what is the best place to start out at right now. Apply to a number of different places and wait and see if and where you get an offer(s). Then comeback and ask, "which of these places would be the best place to start out at." Until then your first priority should be getting in the business. There are a million guys like you applying and most of them have a 4 year degree these days.
Jones is pretty desperate to hire people these days. Not the worst place to start, but I've heard even there they are starting to require a 4 year degree more and more.
