PLLC, Professional Limited Liability Company: some states do not allow certain professionals to form an LLC that would limit the liability that results from the services professionals provide such as doctors, medical care; lawyers, legal advice; and accountants, accounting services; architects, architectural services; when the company formed offers the services of the professionals. Instead those states allow a PLLC or in the LLC statutes, the liability limitation only applies to the business side, such as creditors of the company, as opposed to the client/customer service side, the level of medical care, legal services, or accounting provided to clients. This is meant to maintain the higher ethical standards that these professionals have committed themselves to by becoming licensed in their profession and to prevent them from being immune (or at least limit their immunity) to malpractice suits.
If you are a professional photographer or just have a deep-rooted passion for it, you can make money from your pictures on photo selling websites. All you need to get started is a camera, preferably a digital SLR with a minimum of 8 megapixels, and a computer. Once you have established yourself on websites such as GettyImages.com and Flickr.com, you can setup your own website with a list of your watermarked images and their price per unit.
