Search the Internet for work-at-home opportunities and the results are pages deep. It's true that you can use the Internet to increase your income and do it from home, but proceed with caution. There are plenty of scammers who make money by taking yours.

There's no quick way to Internet riches. To earn money, you need to provide some sort of service. Like real-life jobs, you may need to pass a test or a background check before getting hired. How much you can make depends on your skill and experience. Where possible, I've listed average pay rates.

FREELANCING

Freelancing isn't just for writers. Designers, programmers, business professionals, engineers and administrative assistants will find opportunities.

Many small sites list freelance opportunities. Some let you bid on projects for free. For more opportunities, try www.Elance.com, www.Guru.com or www.Sologig.com. Expect to pay $100 or more for annual membership.

As a freelancer, you won't have the security of a full-time job. But you set your own rates.

CUSTOMER SERVICE

If you're experienced in customer service, you can do this virtually. In addition to your own computer and a landline, you need a quiet environment. You can pick your own hours. You'll earn between $6 and $30 per hour. Try www.Arise.com, www.LiveOps.com or www.WorkingSol.com.

VIRTUAL CONCIERGE

Virtual concierges handle errands and inquiries. You may be assigned mundane tasks like scheduling appointments or wacky ones, like locating clothing donned by a movie star.

You need strong customer service skills. Try www.VIPdesk.com. Or, if you can sell yourself, start your own service. Compensation starts at $14 an hour.

TRANSCRIPTION

Have strong typing skills and a good command of the English language? Experience is required, and you must type 75 words per minute. Visit www.Tigerfish.com and www.ProductionTranscripts.com.

DIRECT SALES

If you're good at selling, consider direct sales. Many companies have programs, and it isn't just Tupperware or Avon. You can sell in person or online.

The Direct Selling Association at www.dsa.org will match companies to your interests and offer advice. Visit the individual companies' sites for information on their programs.

WATCH OUT FOR SCAMS

You'll find plenty of scam artists when you look for work-at-home opportunities.

Be wary of companies that promise extraordinary sums for little work or opportunities that require a substantial investment. In most cases, there shouldn't be up-front fees to get started. With direct sales, you may need to buy products. Don't pay more than $500. And make sure the company will take back unsold stock.

Before you get involved with a company, do an online search of the company name and "scam." You'll see if others have had bad experiences. Also, check the Better Business Bureau at www.bbb.org for complaints.
