You can be in for a tough time putting your content together for all your marketing needs if you are not familiar with what is required. There are a number of freelance websites out there such as Elance.com and Guru.com that help you connect with potential freelancers that can take up your writing work and give you the required result. However, finding the appropriate content writer goes beyond just posting an ad on these freelance sites. Consider that you hopefully know what kind of writer you require, so then you have to evaluate very many things and writers and make the best decision.
Of course it is possible to find the scam artists among freelance writers, and they are just non-writers pretending to be writers. Anything that does not sound quite right such as delivery time is not appropriate for a large content order, etc. This is your business that will be affected, so you need to take good care of it.
It is totally fine to ask anyone to give you at least two or three references you can actually verify. This is important because unless the freelance writer is just beginning their career, they should be able to give references to their past employers that you can get in touch with. It may take a day or two to verify references, but it is worth it and you should do it. The most important thing you can do is have your plan worked out and written down, and that way you will see exactly what you need and do not need. If you feel that this could wait, and for now you are better off handling your own work, instead of outsourcing it to a professional, then wait by all means. Finding the perfect freelance content writer is really not all that difficult when you learn a few things and prepare. Keep in mind that using content writers is not all about how well they write.
