Business Description - Copyrwrite

My business is a recent start up and requires some professional copywriting skills.

It is required to write:

1) Two types of description of the business - for B2C and B2B parts of the business (key)
2) Current offer description (possibly)
3) Sales letter for B2B (possibly)

The key is to communicate benefits in a clear, trustworthy and winning way in order to make the business proposition attractive for B2B and B2C parts of the business.

Writing description of the business will require analysis of the business and defining benefits of the business (this has already beed done, but a professional point of view will be needed).

Successful candidate will start with point 1 (business description) and it will be later decided whether the job will be extended to points 2 & 3.
