Ask HN: Coworking space in Mtn View Downtown: castro street

I am thinking of starting a small coworking space in mtn view downtown. (5 minute walk to caltrain)

Quick questions I have :

- The space is 500 Sq Ft. I am thinking of limiting the max membership at 20 ppl. What is the ideal rate ?

- Facilities will be : coffee station, water and high speed internet (in downtown, you can get most of the things).

- Which company can provide an excellent internet service (authenticated to paying members). Who can set it up completely?

- What license I need?

This is my first foray in business, (full time employee otherwise). What advice can you give?

Thanks
