You should have experience creating amazing slideshows. Send me examples of work you have done in the past. I need to get this done as soon as possible and the slideshow will have at least 60-70 slides. I will give the text to prepare slideshow. This slideshow needs to be converted into a video with audio in the background. Audio will be given by me and I will be speaking about 8-9 pages of text in the audio with some music. The sideshow should explain what i speak in a video format because this will be uploaded to youtube too and will be the main video on my website on front page. The core expertise you should have is good ppt skills and good design sense. There are softwares to help create video out of this slideshow which we can use. However, the main skills required is creating good slideshow with animation effects. So please send me examples of amazing slideshows you have prepared and tell me if you have any such examples as part of your freelancer portfolio or reviews. You also need to have a good business sense. This will be an hourly work because I like to align your interests with mine because I need work of amazing quality and you will use my time and screen tracking software to work on this. You can imagine how much time it will take to prepare 60 - 70 slides and make a video out of it so it is really good amount of work and I need a dedicated resource who can finish off work working 8 hours a day for the next few days.
