zip code request

Hi,

I can buy premium theme. But I have queries. Can you please
answer my queries?

Can you provide zip code validation support?
Just take zipcode 80911 as an example
(a) For pincode 80911 I want to sell only through online payment.
(b) For other pincodes I can provide both COD as well as online
payment options.
(c) Also I want to add COD and Online Payment as per order amount.
Suppose if order amount < $25 then both COD and Online Payment
option available. If order amount > $25 then only online payment
option available.

Can your theme provide such above support or not?
