if you can find a well-recommended local joiner, he should have the skills to do do a nice job. I pay mine a day-rate so he has no reason to skimp or rush. He's £130 a day outside London, I would have thought £150 would be OK for you.
I recommend having the skirting taken off first, and preferably new put back once the floor is down (unless you have ornate period joinery, in which case put the old back, preferably after stripping or sanding it). It will look good and be easier to paint or stain to a good standard. I had the architrave and windowboard done to match. Ask the joiner to explain why skirtings are scribed. If he is, he'll know.
