Amazon.com is expanding its Amazon Home Services business, a clearinghouse for hiring independent contractors and small businesses. The online retail giant is competing with companies like Yelp and Angie’s List to connect consumers with local businesses Amazon says it has vetted. Among the help you can hire are home improvement contractors, home theater installers, French teachers, and even aerial yoga instructors. Amazon Home Services is already available in New York City, Los Angeles, San Francisco, and Seattle. It’s now opening up in Miami, Houston, the Dallas-Fort Worth metro area, Philadelphia, Phoenix, San Jose, San Diego, and Washington D.C.
