Custom Fabric Pursuit

Hello all! I was hoping one of you amazingly crafty, creative ladies/gents would be able to assist my fiancé and I with a little quest we've undertaken for our wedding

For our elopement, my fiancé is having a custom suit made, but we would like to have the fabric lining on the inside be as unique as our personalities. Unfortunately, we're more idea people and not creative in the very least. We have many ideas in mind for what we want to design (unbelievably nerdy), and I know there are companies out there that will work with you on creating fabric patterns, but I was wondering if any of you have worked with any such companies or had luck on Etsy

Any advice is greatly appreciated! <3
