Make an App Promo & Explainer Video

Hi there. I have an idea for an app that I would like to get made but in order to explain it better to users I need an App Promo & Explainer Video. I have a couple of samples that I would like to share and I would like my video to be made according to that or you can infact use the same videos as well: For Promo: 1) [login to view URL] 2) [login to view URL] 3) For Explainer: (You can use combination of these) 1) [login to view URL] 2) [login to view URL] Now, if you would like to know more about what kind of app I am getting developed, you can find the details on [login to view URL] I can explain you things in more detail in private. I have a low budget so Talented Beginners / Newcomers on Freelancer.com who are looking to get a head start are very much welcomed here and will get a good review at the end. You must have examples of your previous work done in After Effects, Graphic Designing etc. And if we get along, I might be using your skills on later stages as well. Many thanks Saad.
