Need Explainer Video For A Presentation job

I have a big marketing presentation coming up, and I need to deliver it in two weeks to our clients. I have to include all the main points in my presentation that will interest the clients. I want my presentation to have a perfect video explainer that will demonstrate each and every point with much more clarity. For this purpose I'm looking for a professional video animation company that can provide the excellent explainer video services up to the customer's satisfaction level. Since I have a very short timeline I want to hire a place that can complete the work within the provided timeline, and must be able to deliver me the explainer video at least a few days before the presentation, so that I can review it and suggest changes if there is a need for that. It will be really helpful if someone can kindly suggest a professional place for me to avail the video animation services.
