Applying r3, need some advice

So I am in a tricky situation. I have been living and working abroad since I graduated from UW-Madison in 2008. I had a decent gpa (3.24), and just did well on my GMATs (720 47/42 QV split).

For work, I lived in China for three years, got fluent in mandarin, and opened a poker club in Shenzhen. Sold it 9 months later for a tidy profit. Then started a cheese manufacturing project in the Philippines, for which I wrote a full B-plan, projected financials, raised some private equity, and got a $1 million dollar commitment letter from the US government. The project went sideways in January when we had a construction budget overrun that was going to eat into our working capital, and long story short, the project is on hold.

I took a GMAT with no real time to study in January, but got a 620, so I couldn't apply to schools with late r2 deadlines. I just got my 720 on 2/28, so it's only r3 or next fall.

I want to apply to schools that have strong entrepreneurial programs, with good access to VC firms and solid start-up competitions etc. International ties are great too, but not necessary.

With all this in mind, a couple of questions:

(1) How much more difficult is it to get into the top level schools this late in the process? (I am looking at Fuqua, Darden, Ross, and a flyer on HBS - have legacy, but feel like more realistically George Washington, Georgetown, maybe Tepper are the schools to aim at)

(2) If it is going to be more difficult, should I wait until fall to apply, or will the 6 month gap in working look really bad on an app?

(3) Anyone have any dark horse schools that are less well known but have solid entrepreneurial programs?

Thanks guys!
