I am a Computer Technician, & I have a client that I have done work for on the weekend in the past.

He has asked me to come over this weekend to cleanup the computers & install Anti-virus software. But in addition to that, he wants me to help edit a video for YouTube, create a Wikipedia page & update his linked in profile (and some others he can't think of right now).

I am okay with doing the computer repair work, but I really don't want to do the other things. Even though I am capable of doing it, it's not really something I enjoy or am passionate about. And not worth using precious weekend time on.

How do I go about telling him I don't want to do those other things. I have a hard time saying no to people.
