I agree with the other posts. At your age and is actively running your own biz, it is unlikely you will be gaining too much by getting an EMBA. Nothing better than learning on the job and getting practical exp.
A cheaper way is to hire someone with a top MBA into your organization and see if he/she really adds value.
With that said, in case you do want to do it, MBA or EMBA programs from Harvard or Stanford might be the best choices because these two programs are geared toward entrepreneurs like you.
MBAs from other schools such as Wharton are focus toward early to mid career candidates who like to work as highly paid employees on wall street or in Fortune 500 companies.
