It really just comes down to how well it's painted, and if it's a ready painted model someone is trying to get rid of versus a model you are actually commissioning to have painted.
If an army is painted poorly enough or incomplete enough that most people are just going to strip the models, they'll be worth less than new-in-box models.
If an army is painted well, and the WHOLE army is painted and ready to play with, it could go from anywhere like the new-in-box price up to several times the new-in-box price.
If you're actually getting something custom painted, places can give you quotes, but it usually comes down to them estimating the number of hours it'll take them to paint something and some hourly rate they want to be paid. If you want a custom painted Hive Tyrant even done to a poor quality, it might still take 4 or 5 hours to build, clean and paint, so expect to pay someone 4 or 5 hours worth of wages. If you want the same models painted to a high standard where they might spend 2 or 3 days on it, then expect to pay 2 or 3 days worth of wages to get it.
Commission painting is always going to cost a lot more than buying a ready painted model that someone is just trying to get rid of in order to clear out a spare room in their house. Some years ago friends and I bought off ebay a few fully painted
WHFB armies, and they cost roughly the same buying those models new in box, but it was a fully painted army so we bought them just to play with them as-is, we had no intention of adding extra models ourselves.
But that was someone trying to get rid of the models, not a commission painter, for a commission painter there'd have been hundreds of hours involved in painting that many models even to a poor standard, so if we'd bought those exact same armies commission painted they'd have cost thousands of dollars more than the new-in-box price.

Commission selling is a terrible way to make money. You might see something that looks overpriced, but if you think "how many hours would this have taken to do?", subtract off the price of the unpainted models, and divide what remains by that number of hours, most of the time the effective hourly rate is terrible.
I briefly considered doing commission painting many years ago (even though I'm not a great painter). I spent a few minutes calculating how much I could sell models for versus how long it'd take me to build and paint them and quickly realised I could make more money doing literally anything else, it was so bad that it made working as a burger flipper at McDonalds look like an intelligent career choice
