I am a rated PowerPoint expert, and have completed a number of presentations at "short notice" but not at the budget level you proposed.
Happy to work under a Confidentiality and Non-Disclosure Agreement if you want, and able to produce by Sunday subject to you paying the fee into the site and sending me your existing material tomorrow.
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 across five freelance sites, I have good reviews from international clients,
Not clear whether you have an existing template that you want to use, or want something different?, And how many slides are involved?
As this project is 'restricted' I cannot send you any samples to let you judge for yourself unless you initiate a chat with me.
Hope this is of interest,
Bob Allen-Turl
