Thanks all for your advice, the idea of this trip is looking more and more favorable due to the likelihood finding a good graduate job is going to be tough. Not only will it be a fantastic experience, as traveling has been a passion of mine, it will allow me to experience so many cultures, away from the beaten tourist track. I also believe it will teach me so much, may graduates don't learn. I would collect money for charity, b setting up a web page and look to get some exposure. I would then hope that once completed, this may open some doors, and look good on my CV, providing potential employers something different to look at whilst wading through the numerous candidates.
The timeframe will be important, I suppose I would aim to reach India around christmas time, avoiding the rainy season.
