I enjoy working for clients who know what they want as I make certain the tone and content of my work fits your needs and your project's voice.
In addition, I specialize in rewrites -- recomposing and saving projects that failed to satisfy your needs in the past. In addition, I include a revision pass in the original cost of my work to add any changes you'd like to see after I complete the original draft.
I usually invoice half in advance and half on final receipt of my work, so both of our interests are covered. However, I can work out other terms.
