Presentation improvement

I have a presentation that i have written in terms of content and some graphics( but quite poorly put toegheter very quickly) it's for a presentation at a job interview. I really need it just improving and making it look nice, and a lot to improve on the graphics and add in animations so the arrows through the processes could be clicked through as I talk through the presentation. Is it possible for you to help me with this? there are 20 slides but all graphs and some are very similar to each other. How quickly can you get this done and how much? Thank you

Many thanks
