Wedding First Dance Medley Song

We are recently engaged and we are looking for a unique medley song that is a mashup of our 3 to 5 favourite songs ideally needs to sound like 1 song rather than 4 separate songs this can be done through a band or using original songs. We understand it may be difficult to get them all due to the ramge but would be really happy if we can get a bit of at least 3 to 4 of the songs if possible.

Dan & Shay - From The Ground Up
Ed Sheeran - Perfect
Ed Sheeran & J Balvin - Forever My Love
Celine Dion - The Power of Love
Shania Twain - From This Moment On
