CSS work - Need update to CSS for dynamic buttons

I need a CSS guru for this project, and possibly others coming up. We have received a website design that was 'sliced' by another developer, and although its pretty good the other developer is not available to do updates for the CSS work. They gave us some really nice graphical buttons, but they are all fixed width and I need something where the button can grow to fit around varying sizes of text on the buttons. If this is something you've done before, please bid. If not, don't waste your time (and mine). Let me know your background, samples, etc. for this type of work.
