Presentation Slides required

We are looking for a designer who can produce presentation slides for us on a regular bases. Initially there will be a lot of slides to produce but then we would need regular slides created. Also we would require some pop up banners and leaflets for exhibitions we attend. The initial batch of slides are very urgent. Slides to be prepared in Powerpoint, PDF and other formats. We will have a template for each slide which will need to be populated with images and text in the same format.
