Replacing Car Door Handle Hyundai Accent 2004

Hello, I'm going to attempt to replace my car door handle on my car. I'm no mechanic but found a video (https://www.youtube.com/watch?v=1rQg4sDlhCw) and am mildly inclined to technical things so I'm going to give it a shot.

I am curious if there is anyone out there who might be able to finish the job if I mess up or my tools don't make the grade. Shouldn't be more than an hour of work tops and I'd throw you $50 if I did need you to make it worth the time. Anyone thinks they can help, or know someone who might please get in touch through writing.
Thanks!

Best, Frank
