Desktop or Web App to Help Personal Training Business(repost)

I'm looking for a coder to design either a desktop application or web based program that will help me design a diet plan for each individual client. It will consist of a couple prompts with 3-4 probable answers and then will display the recommended diet guidelines while giving the exact amounts of each food (~20 total foods) for each meal for a total of 3 different diets per client. I would also like the ability to convert the output straight into a pdf. Please contact me for other details/questions.
