Need one wedding dance song mixed with one or two others

Wondering if you'd be able to mix in some upbeat music into our first dance wedding song so that it's more of a mashup style song. We've chosen the first dance song of Forever to Go acoustic version by Chase Rice (2m 57s song on spotify). We were thinking it would be fun to have a mashup start sometime around the 1-2 minute mark where the song switches to something more upbeat for 30-45 seconds and then switches back to the original song (around 2m 22 of original song). We are starting to look into some upbeat well known songs for the mashup but open to suggestions. Please let us know if this is something you'd be able to create or if not if you can suggest someone to contact who would be able to create that for us. Many thanks!

Additional info:
I don't need the song mastered. I'm hoping to find a good mixer that can work with my limited budget. . I'm an indie artist. The song has less than 10 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I need it by 25 July, 2023.
