Develop a MS Access Database for online subscription co

We already have a filemaker database but need a new one developed that has a better architecture and connects with our payment system and shipping tool. Current database is around 25 MB in size. Database functions needed: -serves as our CRM and hold all account information including payments dates, amounts, shipment dates, tracking numbers, notes about each shipment, refunds, credits, notes, shipping address, etc -connect via API to our recurring payment system Recurly -will need to be programmed so that payments are broken up into "x" shipments based on the frequency plan the customer has. Example: Customer A pays $100 every 28 days and has a weekly frequency so 4 payment lines will need to be created, each being $25. -corresponding shipment dates will need to be programmed for each payment based on state and date of payment -payments declined will need to be routed to a dashboard so that once payment comes in we can manually enter in the shipment dates -connect via API to Shiprush or other Fedex system to generate shipping labels and store tracking numbers for each shipment date -reporting, be able to run a report selecting any combination of field or fields -search function -auto input all new customer data -connect via API to Amazon to input all customer data, payment, order #, order date, shipment date, product ordered, shipment tracking #
