Convert a basic University Presentation into something that 'pops' visually

Job ID: 36312587

Budget: $30 – $250 AUD

I did a basic university presentation, but would like to know how much and how long to professionalise it and make it 'pop' for when I use it through my company.
Attached is the basic using cliparts and free images. Also attached is my company logo, which I would love to incorporate with front cover page, a colourised theme through and some stylings around font / template.
Please let me know what it would cost, how long it would take and an any example of previous work (before and after).
