About 2 months ago I was asked to make a charity website for a friend, it was only going to be a html/css website ie. No need for PHP, JavaScript etc, being a friend I offered £60 for the website, we decided the look of the website and I created the graphics etc, the website was done.
Recently he asked me to completely change the look of the website (no problem), ie remodelling and new graphics but now with what he wanted it required PHP, user access, JavaScript, ajax, DOM manipulation, the lot pretty much as he wanted an application form (over 30 fields), a donation payment form, a lot more pages than before, and I'm still under the impression he thinks he only needs to pay £60. What can I say, politely to tell him it's really not enough for the work I'm doing?
