Graphic artist do all the drawings on computer in a professional drawing studio (cost = hundreds in not thousands of dollars). To get a decent job, you''ll need good work. People won''t hire you unless you prove to be a worthy asset. About finding a job in the field: what field? game programming, advertisement, etc.

Game programming is probably the easiest to find a job in. Companies are always looking for talented graphic artists.

Graphic Artist is like any other skill based job. You cannot know how good you are/can be until you try ... and pratice / experience always pay off large dividends. Think of it as wanting to be a musician. Nearly anyone with average or better dexterity and decent sense of timing / rhythm can become a drummer, the major deciding factors are how much you WANT to pratice / improve, and whether or not you have the imagination to push the field in any way. If all you want is to get paid for doing graphics work .. all it takes is enough skill to demonstrate the ability to produce and enough perseverence to actually produce output on demand. Actual pure ability or talent really just distinguishes between different levels of artists, it doesn''t take a master to get the job done, but a company seeking to break new ground will find it worth their time / money to invest in one . Best wishes.
