This is not enough money – not getting any clients is a good thing.
The monthly thing is going to lose most people even if they were interested.
There really isn’t much of a market in low end websites – between the SaaS builders, DIYers and overseas offers this isn’t where you can really make any money. I’d suggest learning and then trying to come in higher up offering something that is beyond what a computer savvy friend could do.
Either charge enough that you can include delivery in the price or make it explicate that delivery is an option and that it costs $x extra. You can’t offer to deliver and then charge them.
Also if you need someone to drive you then that is a problem. Personally I am a big fan of using local couriers – for $6 to $20 you can get something delivered without wasting your time but I’m not certain that would work for paintings unless there is a way to package them so they don’t get damaged.
I personally would not offer delivery if I needed to ask someone for a favour to drive me.
