Hi! It sounds like you know exactly what you are looking for. That's perfect! I can help you with your powerpoint presentation and eventually, if you like my services and designing, I can also help convert it to a video for the TV.
As a side note, it is also possible to convert powerpoint slides into JPEG images, put them on a USB flashdrive, and play them on a TV screen, either in order or random order. There is a company I have worked with that has a weekly slideshow and this is how they create and show their powerpoint.
I've been working in Powerpoint and graphic design (Illustrator, InDesign, and Photoshop) for the past 10 years, and have created many powerpoints with custom slides. So I am confident I can help you with your powerpoint. Also, I always finish every project I start, so you would not receive an incomplete powerpoint from me.
Feel free to look through my portfolio, read my reviews, and contact me if you have any questions. I'm here to help you complete you powerpoint to the best of my ability and to your satisfaction.
