If it is suitable, hire them. Simple :)
Even then, however, it is most important to CLEARLY communicate your needs, down to the nitty gritty detail. 85% of all copywriting problems come from the client/company not communicating its desires and needs clearly enough for the writer.
References are always good as well, if you feel the need to really cover yourself prior to hiring your chosen content provider.
Happy hunting! :)
