I know some methods for getting outsourcing works, like freelance site,forums,site marketing etc. What are the other methods ?
Go to US, UK, CA, etc. Make a firm. Get work by their rates. Back home. Make Indian firm with local rates. Give job to them. That is the way.
That's where I can't help. I mean sure it's possible. Lot of people did it, so why not ? How exactly ? Probably you need to visit it somehow with that goals.
Credit for business ? Or to find a partner in that countries locally ? But if that's your goal work and save 90% of earnings.
