You start of with eight farm cash, then whenever you level up you get 1 more farm cash and you can also complete surveys that you will find under the farmville screen this will depend on what survey you complete but you can normally get around 2 farm cash. You can also use your own real money to buy farmville cash.
You can't !!!!
A scam, don't do it.
You get 1$Farm Cash for every level you move to. You can take surveys and get 2 free farm cash occasionally. I have taken them provided by Bing, AT&T etc. But, beware if a survey offers an extraordinary amount it is a scam. The true offers appear just below the area where your neighbors profile pictures appear. A scam offer will have for example Farm ville Christmas Get Some (on the Home page ) If it is truly a farm ville offer of any kind it only says Farm ville with the corn logo under the picture. Farm ville never gives cash except when you level up. But Bing or other companies will do occasional promotions.
If your on farm ville that's on face book you can ask your friends to send you free stuff!

As far as I know, there's no way for you to open farm ville on Twitter. Farm ville is an application for facebook, thus allowing only facebook users to access that.
