This depends on several factors.
1) how much meaningful extracurricular activities do you have?
2) how much leadership have you shown in and outside of work?
3) what are your post-MBA goals?
It's a good thing that your GPA trended upward, but that 2.8 is hard to neglect. If you have time, I would highly recommend you doing an alternative transcript. By taking a few business courses (accounting, econ, statistics, etc) and getting A's in them show the AdComs that it truly was an immaturity that led to your sub-3 GPA. If you don't have time for this, no problem, but know that the 2.8 will certainly hinder your chances.
At this current stage, without knowing the answers to the three questions I posted, I suggest you look into the top 10-30 schools. It will undoubtedly vary between schools but schools in the top half of what I said will be harder and school on the bottom half will be easier. Go ahead and answer the questions and I'm sure we can narrow down the list a bit. (by the way, congrats on the 700 on GMAT!!)
