Designer needed to create range of corporate stationary

Industry: Business
Design details: We have nine client/customer facing documents that we want modernised with a sharper design, to match our new website. About half of the documents are single page (i.e. invoice), and a couple are 6/7 pages (i.e. staff appraisal form).

The design style we are looking for is sharp, stylish and smart. The client described the brand as "an Audi, in grey, gold and white".

The first task is to agree the design concept. To do this, we will need you to create three different concepts on one of the multi-page documents. Once the client has agreed on the design they like, it should be fairly easy to do the other documents.

We have a few ideas, and can send you logos, colours and fonts to get you started. We will then need three concepts delivered by Monday 9th, with the rest of the project finished within 3 days of receiving feedback.

It would be good if you could send a sample of similar things you have created.

Thanks

Charis
