Avinashi, I am a rated PowerPoint expert with clients on five freelance sites. But to let you judge for yourself whether I can help, I am sending you two PowerPoInt slides on the next message where you can 'Drag And Drop' objects in the slide show, which is what I assume you are looking for when you refer to 'interactive?
I can work under a Confidentiality and Non-Disclosure Agreement if you wish, and can start as soon as you pay the retainer Milestone into the site and send me your existing material..
I designed presentations for twenty years at a leading multinational, delivering them from Mexico to Turkey to audiences at every level from Main Boards to General Public.
Now working from home in the UK, I have good reviews from international clients.
Hope you find this of interest and look forward to hearing from you
Bob Allen-Turl
