price to shave lower door moldings

[rocky.ca]

Ive seen a bunch of threads about how it looks or how it was done, but if i bring it to a shop, how much will it cost? I need to get it done pretty soon (a little bit of rust is forming, and i ripped off all of the mouldings because they were pealing) Any ideas, dont think it should be much, all that needs to get done is to grind off the knobs and repaint the lower part of the door. any ideas guys?

i'd say go to like a welder to get them shaved off and have the painting done at a body shop bc the bodyshop is going to charge an hourly rate(higher than the welder) to shave them off....although idk how long it would take to do
