@Stone_man 500-600 is sounds reasonable. But what do you mean buy cleaning is it just for cleaning dust accumulated in the laptop fan / blower?
Most laptops aren't very complicated to open or close if you know all the location of the screws, ribbon etc and you have all the right tools. But if you are unsure always get it done by professional technicians.
Contrary to what other dimer ( @Gulag-Survivor ) suggested most of the regular technicians don't always use or need to use ESD (electrostatic discharge) straps, just discharging their hands on a metal conductive surface is more than enough. As @bikidas2060 suggested you might damage a electronic device by dropping it on PCB but ONLY were running current is running through the traces, but if a device is turned off for more than an hour (more enough time to discharge all the SMD capacitors) then dropping a screw shouldn't cause any type of short ( short circuit) between two or more contact points or pins..

It's fair because he is opening a very delicate piece of electronics. He has to disconnect the internal battery and remove the heat sink. Since, he is an expert in that field he ll do it meticulously. Although cleaning process is fairly simple and no nonsense but you are paying for his experience. It's absolutely fair. Otherwise you do it yourself. 🙂
500 is fair for this one-time things since no one does it often.
But I suggest being present during cleaning and monitoring.
you won't damage anything, just go ahead with DIY.
nothing inside is delicate.
screws at bottom are meant to be opened when required for cleaning or replacement of kaput parts.
you can do it.
Depends on the laptop price.
I opened my sasta laptop, cleaned fan , other parts, also, gave thermal paste myself.
Major things to take care if DYI.
