It depends whether you want to spend money or not. For example, I was researching this issue and found out there are 2 possibilites :

1. You can find ready animations in youtube and google ( but they will be kind of overused by different brands). If it does not bother you and you like the result than fine. It is very easy to efit them in Adobe Premiere.
2. or you can find on upwork a freelancer, tan it will cost you some money ( but always try to research so they would not use the same patterns like in first examle and sell you for overprice) .
   I can give you example which I ordered on fiver, it was just 5$ but very nice . I just can't find it now since it is 1 am at my place, but I will add to you other post later ok ? :)
