Powerpoint Template Design

We are looking for someone to design some Powerpoint templates for us to use in presentations. We have a well established brand and logo, but are suffering with presentations where we have to use Powerpoint. Our current templates are full of photos which make the file size very large and impractical.

What we need is a full set of slide templates, i.e. title slide, title with content, section header, sub-section, two content, comparison, title only but not based on an existing Microsoft theme and that are created as a true Powerpoint theme.

Timescales are tight - we really need this within a week, so someone that can turn around quickly is essential.
