Hello there,
I do advise that you do this process yourself. It is easy if you learn a simple but professional video editing software such as Wondershare Filmora (check on YouTube). I can send you the setup and effect packages so you can download and install it for free.
I will teach you on how to do video editing (cuts, trimming, transitions, effects, audio, color correction, basic motion graphics and text and greenscreen removal).
Let me know if this would be helpful for you
Thank you and have a good day
