Target Goal Post MBA: Consulting or in a Strategic Role in Corporate

My GMAT score isn't ideal and it has been challenging putting away time to study with my current role. Working in sales means that I have to spend a lot of my non-working hours still thinking about work. Otherwise I'm not committed to achieving targets.
I've held a lot of different roles at various organizations but can all be explained. Partially it was because I wanted to explore different industries or discover what I really like to do. Partially it was also because of unforeseen circumstances such as restructuring.

I think my background is decently well rounded and I have been able to leverage what I'm learned in my previous experiences in every new role I've taken. I'm excited about improving performance and solving problems which lead me to this post MBA goal.
I haven't seen too many profiles here that comes from a consumer packaged goods background and I'm not sure if this is an unfavorable background.

Here are the list of schools I'm looking for based on their employment reports
Duke
NYU
Cornell
London Business School
Insead

I would also love to go to Kellogg, Columbia, Yale but understand that my GMAT is very far off. I do want to reattempt GMAT again in 2 months to try to achieve a 720.

Here are the questions I have regards to the application process.

1. Do I have a shot at those 5 schools listed above? If not, is there anything else (GMAT is one) I can do to improve my profile?
2. I'd like to be in for Round 1. However, reading a lot of the posts here, I understand the application is just as if not more important. Should I spend the current time rewriting GMAT or actually preparing for the application?
3. I see that the average age and work experiences of students at these top schools tends to be around 28 and 5-6 years. Since I'm already over the average, does delaying my application hurt my chances?

Thank you,
