I am creating a website for an attorney and now she is asking me about maintenance fees once it is finished. The site is really quite simple with mostly static pages. It has a JavaScript slideshow and a PHP contact form.

Anyway, I didn't charge a normal going rate since I am just now starting out and at this point, just want to get some work for experience as well as some sites to show off to others.

My question is this. How much should I charge for maintenance? Should it be a monthly fee or a one time charge each time I work on it?

I can't imagine there to be a huge amount of work once it's complete. Maybe some picture changes, updating info and things like that.
