Need 50 Hungry Niches- Keyword / Niche Market Research

I need 50 hungry niches delivered in Excel format. Requirements: Each niche will have less than 5000 competitors according to Google quotation search. You must know how to check for this. Each niche must be a "hungry market". If you're experienced with IM, niche marketing, etc., you'll know what I mean. REQUIREMENT **** You must know what constitutes a "hungry market" and how this translates into buyers. **** I can't pay for a report of random keywords. I need 50 keywords which represent hungry markets with buyers eager to buy in that niche. Often these markets are subsets of much larger, and very popular markets. Please let me know in your quote your understanding of a hungry market. Also let me know which software you plan on using or how you plan on devising list. Each niche should have 100 or more searches a day. The more the better, as long as the number of competing sites is below 5000. Please deliver report of 50 niches in an excel spreadsheet including the number of competing sites in Google competition search, and the number of searches per day each. Need quick turnaround. If work is good this could lead to several assignments in the future.
