3 articles + 1 press release

Hi, I have a total of 4 articles to be written - with different deadlines. 1) Press Release - about 400 words. Some knowledge on sports medicine and health tourism would be good. Deadline Monday 14 January 2008. 2) 3 articles - 800-1000 words on rainwater harvesters and what is the importance of rainwater harvesting. Need articles to persuade the general public to value water in a country that has more than 80 inches of rainfall per annum. You let me know how much time you need to do this. I will be able to give you some information to kick-start the press release but you will have to do your own research for the rainwater harvester articles. These articles will be used for the local media here so they have to be original, no plagiarism, no old stuff that you've written before, no copies. I will give further information on what I need via PM to the shortlisted bidders. I would prefer the same writer to do all the 4 pieces but adherence to the deadline for the press release is extremely important. Thank you.
