Redesign introduction Powerpoint presentation w/ better graphics, layout and content

We are a Value Added Distributor selling compatible network accessory products globally.

We already have an introduction powerpoint presentation however we would like to:

1)Improve the format and graphics. Some of the pictures/graphics we have chosen could be better and less generic.
2)If possible we would also like to improve the copy/content.
3)We would like the document to have a more modern feel, look glossier and incorporate the company's colours if possible, but we are open to alternative colour themes.

I guess this really requires a template change and some minor changes to the layout of each page.

Should you wish to see a copy of our current presentation please let us know.
