Powerpoint Template

I already have a very simple Powerpoint template of 4 slides. We are facing some issues.

We need to resolve these issues. The template is very simple, no animation or special effects.

Some Issues we are facing;

- The text can not be edited

- Need to add 2-4 new slides ( I will provide the design in PDF or illustrator version)

- Need to add standard header and footer, with slide numbers

Super urgent work. Need a designer who can start immediately.
