Ok here is the deal.Google is becoming a faggot aka it is starting to get really hard to extract big amounts of links from google.Thats is why I recomand some other search engines like badui,sky.com,yandex etc.
Also there are over 10 different "google enhanced" search engines online that do not ban by ip if you scrape nor you need to use proxy to scrape from them and they still give you the result from google aka they retrieve google result for you.
You should check out list of search engines that Hrefer has,it is pretty awesome list witch you could implement with Zennoposter by making some simple template for extracting links.I say this about Zenno because I noticed that many of these "google enhanced" search engines have very simple source code unlike google and the result could be parsed with only few regex matches.
Or you could go to freelancer or odesk and higher a programmer that will probably satisfy your needs.
