If the GM lets you make a character who has already earned some experience, simply make a character as usual and then grant her that many Advances. A Veteran character, for example, has 40 Experience Points, so you would make a normal character and grant her eight Advances.
Additional goods, equipment, or other assets must be determined by the Game Master and the particular setting. As a quick rule of thumb, a character's starting funds double with each Rank after Novice.
