I think that it depends on your needs. I think that it will be enough approximately 5k dollars per month. I also decided to make a pretty website for my business and design as well.  I found a lot of different information at https://opengeekslab.com/blog/benefits-of-motion-graphics where are described a lot of new trends. Most business owners are trying to perform their website, application or brand more recognizable. So, modern graphics can help to operate it. Customers or just app users are paying attention to pretty pictures and interesting animation.
