We are developing a new science (biology, agriculture, geography and zoology) website which has a front page and a total of 11 main categories and 110 subcategories. For all these sections (122 in total) we need descriptions. For the subcategories the description should be related to its respective main category. Each of these descriptions should be ca. 300-350 words in total. Since we do not know how much work this involves, i.e., how long it will take you to author these descriptions, we suggest US$500 as a budget which is, however, negotiable.
