I don't know of any silver bullet, but this is something I've spent some time thinking about regarding my own startup. Our approach is to prioritize quality over quantity, to encourage the type of community-driven content we're looking for down the road. Generic or low quality content populating an unfamiliar site can't result in a positive impression on your users. Basically, the challenge is to find someone/people with strong writing skills and domain knowledge pertaining to whatever your site is about. Is that you? If yes, why not just crank away for a week or two on the keyboard? If you're satisfied with the content you've produced, but conclude that you need more, then at least you'll have some sample material to present to prospective pre-launch contributors. I'd be happy to discuss this issue further with the OP or anybody else directly (check my profile for contact info). Our pre-launch content creation challenge is quite different than needing lots of reviews, but it is similar enough that perhaps some mutual benefit could come of a discussion with someone dealing with this, or a similar, issue.
