Pretty much every small business could use a little extra cash and some guidance with social marketing. Luckily, Facebook and American Express want to help. By entering the “Big Break for Small Business” contest, smaller companies can win $25,000 and house calls from American Express and Facebook branding experts to help them launch a sound social marketing campaign.

This is the second year that American Express and Facebook have teamed up to offer this promotion. Last year, five small businesses won cash prizes and the chance to work with Facebook executives for two-day tutorials.

In addition to the money and the face time with representatives from Facebook and Amex, winning businesses can also invite other local entrepreneurs to meet a panel of social media and marketing experts to teach them how social marketing can enhance their business.

A total of 10 entries will be chosen by a panel of judges, and then the finalists will be chosen by Facebook’s voting populace.

You don’t even need to win the big contest to get something from Facebook and Amex: Any small business that enters the contest gets educational and brand-building tools from the two companies, as well as $50 in Facebook advertising credits. If you’re an Amex card member and merchant who enters the contest, you’ll get $100 worth of Facebook advertising credits.

Facebook and American Express also team up to help local retailers during Small Business Saturday in November.
