Filemaker Database Rebuild Specialist

We are seeking a skilled developer to rebuild our existing Filemaker database that encompasses invoices, purchase orders, CRM, inventory management, support tickets, etc. Our existing solution is very old and is in need of a complete visual and functional overhaul. I have some mockups of what I want our new solution to look like and I would love to work with someone who has a good eye for design and experience creating user-friendly layouts. We have an iOS app we used for counting inventory that would need to be compatible as well. We don't currently integrate our Filemaker with any other software, but we have been considering connecting to QuickBooks.
