Google Adwords PPC - Keywords Research

We require a skilled and experienced individual who has had success with Google Adwords campaigns to help us research cheaper relevant keywords.

Required:
1) Find cheap keywords relevant to the software, niche, and market. Currently
keywords cost 40p and upwards. Keywords must be keywords that will get a
lot of searches.
2) Write a least 2 ads so we can split test the ads and the keywords against
them.
