I'm looking for a provider which can offer a service similar to mydomain.com, I should be able to add an unlimited number of domains to forward on external urls in a way which should point anything-you-digit.myname.com and myname.com/anything-you-digit to the same destination url

If the service might also allow to add title, keywords and description for each domain, this would be even better but not required.

MyDomain can offer all this but there's a fee for each added domain while we'd prefer paying a monthly fee for a single Hosting where adding multiple domains.
