Dina,
I can turn your Word document into a GREAT presentation but the "best" price will not be the "lowest price".
Finding the "right" images and design depends on what the slides are for and how you want to use them?
A presentation that runs automatically to make visitors come to your stand at an exhibition will be completely different to slides you move yourself to teach road safety to young children.
Working from home in the UK across five freelancer sites I am a rated Powerpoint expert, and will give you whatever is most appropriate.
You can judge my skills for yourself by the samples attached to the Private Message Board.
I am happy to work under a Confidentiality and Non-Disclosure Agreement, and can start as soon as you pay the retainer Milestone into the site and send me you existing document.
I will also need you to tell me if you have any requirements (e.g. do you have a logo to go on the slides? If so where do you want it and how big should it be? Do you want certain colours? Certain font(s)?)
Look forward to hearing from you
Bob Allen-Turl
