Edit the 40 second video for our landing page

We simply need the video editing so it looks better.
The video is only 40 seconds long and when edited will be uploaded to our landing page.
The freelancer will just make it look more professional.
We are unsure how it will look better, but we just want it to look well on our landing page.
Maybe better lighting and sound perhaps???? We will listen to any suggestions the freelancer has.
The video was filmed on an Iphone 14 with back ground light.
