I have a personal stance on doing professional work for friends.

If they offer to pay me for my services, they get discounts and maybe even a few freebies. If they ask for me to do it for free, they pay full price forever.

I’ll also proactively offer free work for friends sometimes when it looks like they could really use it, with the understanding they’re getting “much better than amateur, but nowhere near my best” when it comes to quality.
