I can't recommend Rebecca Connolly highly enough!
https://www.rebecca-connolly.com/projects
She used to work for the big architectural firms, but struck out on her own a few years ago. She's an interior architect, who will suss out the mechanics of what you're trying to do, project-manage the whole process for you, and then interior-design to make it all look pretty/stylish/whatever your preferred look, at the end. She did my whole house a few years back, but she does smaller projects too.
Good luck with your project!
