PDNS - powerdns problem

I have running PDNSAdmin (PowerDNS) on my machine and use it for free (sub)domain registrations. all is working as it should only there is one major problem: I have wildcarded all sudomains (needed) but therefore when I enter in the mysql db of pdns a zone with only two NS (Nameserver) entries it resolved on www still to the wildcarded DNS and not the the DNS which is setup on the external machine. This will be easy to do for a powerdns expert. Quick job - i am looking more for advise here. if you can help me once in a while afterwards with pdns related questions i am happy. max bid $30, payment after finishing task. no escrow.
