The number of U.S. home foreclosures could reach at least 10 million over the next several years, according to Housing Predictor, an organization that lists foreclosures. During recessions and periods of high unemployment, residential and commercial property owners struggle pay their mortgages and sometimes face foreclosure. Banks, mortgage companies and real estate agencies often need photographs of the foreclosed properties in order to take legal action and/or re-list them.

Invest in a high-quality professional digital camera. Some models cost in the thousands, but a $1,000 digital single-lens reflex probably will give you excellent results. If you can't afford to invest that much, consider buying a used camera.

Take photos of commercial and residential properties and create a portfolio highlighting your best ones. Arrange the photos in a nice-looking folder or binder and include a photographer's statement and biography on the first page.

Create a website with an online portfolio and a description of your background, experience, services and fees. Hire a web designer and/or a copywriter to make your site as professional as possible.

Call, write or e-mail mortgage companies, banks and real estate firms. Describe your services. To hook them as clients, offer a 10 percent discount on your standard fee. Hire a designer to make postcards that show off samples of your photographs and describe your services. Mail them to potential clients.

Attend chamber of commerce events and small business association meetings to network with staff and managers at local banks, mortgage companies and realty agencies. Bring your business cards and postcards to hand out.

Post an ad for your services online, as well as in your local newspaper and/or alternative weekly.
