How to grow Mushroom and market to sell the same

Dear all,
Myself Ashwin Prajapati, just joined Farmnest.com. Presently I am employed with one company and want to have something of my own for earning. Farming has always attracted me and tried to check on Mushroom cultivation many times. Now I feel I must work seriously on the the same hence writing on this forum.  I need insight and guidance from all learned and experienced forum members on how one should go for Mushroom cultivation, what is minimum requirement (finance, land, manpower, any other capital investment etc…) also the market to sell the same.
Trust to receive favourable response.
