Billy Joel Mash-Up for Soloist

I am looking for a music composer with piano skills to create a mashup track combining ‘Vienna’ and ‘Souvenir’ by Billy Joel. The project is for a personal concert, where I plan to sing live with the backing track on 9/21. I want the arrangement to stay true to the original recording for ‘Souvenir’ and be seamless, ideally inserting ‘Souvenir’ at the end with some musical crossover. A good example of the desired style is the SMASH recording of ‘Vienna’ in terms of length and feel. The finished audio must be ready for vocals and delivered by 9/9. I am an amateur singer based in Boston. Remote work is fine for this project.

Budget range:
Up to $100

Examples:
Would love if souvenir was true to the recording and inserted at the end with some cross over. The SMASH recording of Vienna is a good length and example of what I’m looking for.
