Your GPA is quite low - is there anything in particular you can point to (e.g. financial or health issues) to help explain that so the adcom is not concerned? Although your GMAT helps to compensate for the GPA, the adcom is going to be wondering what happened with the GPA & how it will predict the extent to which you will be able to focus and dedicate yourself in a MiM program.
Although MiM program are designed for applicants with little to no work experience, given the GPA it would be great if you could do an internship for your uncle's business & if you want to consider naming that as your post-grad career goal that will help your candidacy as well, since the adcom will see that you have a guaranteed job offer (which is good for their employment stats).
In terms of schools, I'd check out St Gallen, HEC, IE, ESSEC, LBS, Ross, and Duke. You'll also want to check application requirements. Some schools will only accept applicants whose undergrad degree is not in a business subject.
Good luck to you!
