Right - work on the wording, but absolutely keep the sentiment. You are clearly valuable to the people using your skills for their own profit. You deserve compensation and respect for the time and effort you put in. Regardless of how well intentioned they seem, be incredibly insistent on payment for your work. Ideally, negotiate pay before any work is done. If they resist this, you need to walk away.

Ye I agree on walking away - I'm gonna try doing this to future people. If I find they just want stuff for free, I'll just try cut to the chase.
