Take it from someone who wasn't technical and became technical: Do it manually by hand. Get an agreement with one company or group of people to use your "online ordering service" everyday for a week, and then just build a Weebly or Wordpress static site with menus from restaurants that uses a Google Form to process the orders. You then manually collect the orders and hand-deliver them to the restaurants. Do this for 2 weeks, and see if demand keeps up, see if you can get 5 more groups of people (companies or communities) to use this continuously. Once you are dying from the deluge of orders, then you can build it, or hire someone to build it. Trust me, that is the easier way to do this.
