Wendy,
I'm not familiar with AHIMA but it looks like a billing course. If you want to start a business you may want to consider our courses on just the medical billing business. We have a bundle with the two courses that will teach you how to operate a medical billing business and how to market a medical billing business. Many times people learn billing but they don't know anything about the business side of it. As with anything, you must know how to run a business in addition to knowing how to bill. Marketing is the most difficult part of getting a medical billing business going. Our online courses will help with both of these topics including things like how to write a contract, compliance plan, and marketing strategy. This forum is also a great place to get information both from previous posts, and by posting any questions you may have.
Best wishes in your new endeavor!
