Create 4 top10 lists (simple articles)

I need 4 'top 10' lists to be created for a site - www.top10land.com. I will then require about 5-6 per week on-going in the future and possibly lots more. See this for an example: [login to view URL] This is how i expect the top 10s to be created. A good few lines of text for each item. I need a top 10 list of: Printer Manufacturers (Epson, HP etc) Pet Names Promotional Gifts (Pens, paperweights etc) Sports injuries (knee injuries, back pain etc) The best way to do them is to have a look at wikipedia for the subject and then write about each. However, I do not want any copied data from any other site. Text must be unique. I will pay $50 for this set of 4 lists to be done. I would also like them done quickly so that I can make a decision to give the right person the weekly 5-6 jobs to do.
