Just for informational purposes...
I offer this as a paid service. Site is https://secdns.posix.co.za.
Secondaries: London (TeleHouse) and Johannesburg.
IDN aware (Puny/UTF8 names), IPv6 Connected, TSIG Management system
(supported/encouraged), DNSSEC aware (can view your DNSKEY records -
does not Sign domains).

Cost is R3 (Three South African Rand) a month per domain. That's about
US$ 3 a year.  For five or less names, I probably would not bother
charging. I've also done "Service Swaps".

Its always a good idea to have your Nameservers geographically dispersed
to try to reduce the number of any single point of failure. ie - not
just same Machine/Rack/DataCenter but also not the same City, IP-Block,
ASN, Transit Provider - etc.
