Copywriter for job descriptions and company profiles

Hi, looking to engage with an copywriter that can assist me on my need.

My business is a national uk job board business, i am looking to develop a value adding service for the job board., where a copywriter will draft job descriptions for companys roles that will include key words and offer a professional up skill from there current job descriptions.

Also looking for the additional work of company profiles being drafted on selected business. Offering a positive portrayal of the company covering areas such as there values and community and social policys etc.

Would love to establish an ongoing relationship that is more then a transaction, please if you let me know how pricing structure is best suited to you in your reply and any idea of costs much appreciated.

Many thanks

Neil
