Copywriting for new Website

Hi I need some help getting the wording / content for my site. Initially 3 pages of text required.? These will be roughly based on 3 sites doing the same as me, but made for my site. We will be targetting 3 or 4 keywords, so the density of these needs to be about 3%. Looking to target big corporate buyers, but also smaller jobs too, so got to be a good balance. Needs to sound punchy and fresh.
