domain name sales service

Hi there! :)

I don't think I know of a free domain but you may take a look at the following link.  Most of them are affordable and it might be what you're looking for.

Reference: https://www.namecheap.com/

have a look at this list

https://www.icann.org/registrar-reports/accredited-list.html

these are the actual registrars. better stick with them than retailers. beware that they won't all do all the possible top level domains

you will also find a smaller list of registrars on the site of afnic, apnic, latnic ... whatever nic you depend from. each top-level domain is handled by one of these organisms. most handle registrations directly. others will provide a list of official registrars.

pls note that i will not buy domain name;
i am asking how to sell my domain name?

That would depend on the domain. But most domains are worth next to nothing

thnx to all
