Exterior work lives or dies on preparation. Loose paint has to come off, bare wood and bare metal have to be primed, and every gap that lets water behind the surface needs caulking before a topcoat goes near it. Skip that and you are repainting in two years.
I work with the weather rather than against it. If the forecast means the coating will not cure properly, I will say so and move the day rather than put paint on that is going to fail.
Exterior jobs are quoted after a look at the property, because condition drives the price far more than square footage does. Fences and railings are usually priced per section, which lets you take a long run in stages. Repairs found during prep are quoted before they are done, never added silently.
Tell me what you have and I will come back with a written quote.
