How to successfully obtain an entrepreneur visa (in Spain)

Hello,

The first time anyone called me a serial entrepreneur happened last January, in Madrid. The truth is I was pleasantly shocked at how proud it made me feel about myself. I had flown in from New York City for five days to look for apartments and decide if I really wanted to move to Spain. Although I attended school in Madrid for a semester when I was an undergraduate, moving from New York City was a big step- especially since I had no visa, few friends and wanted to start another business.

Please help.

I didn't find the right solution from the Internet.
