Chris, (If I may assume that's your name!)
,
there's a "sticky" thread at the top of this page all about training. Some is a little out of date but much is still valid.
This question regularly gets asked so forgive me for being brief.
Yes, you need a commercial licence in order to be able to earn money from flying. You will be very unlikely to get any sponsorship (unless you are fortunate enough to be able to be trained by The Queen!) and jobs for low-hour, inepxperienced pilots are very few and far between; becoming an instructor is the most likely route.
Cheers
