I need a FileMaker pro to write FM database code

I am seeking a Filemaker Pro developer who will write me a FM database program. I have an excel sample to guide you. I need the developer to also know how to create an APl to talk to SHOPIFY. This developer will build a foundation program that I will be able to have other FM modules incorporated into in the future. This program will need to be accessed by PC, IPAD, IPHONE, and macBook Pro. This is a comprehensive project that a beginner is not knowledgeable about. The budget is listed below. I have many more projects to build. Experience is key and the samples sent to me must show more than templates. This project is about creating an MRP to talk with FISHBOWL software. The Filemaker will be a stand alone MRP system. Please review the excel file attached. Let me know if you have any questions.
