Need help creating a web app from my Google Sheet

Overall challenge: I am looking to create a chocolate recipe calculator built on a Google Sheet. This calculator needs to be implemented on a website so that my clients can use it. I am looking for someone who can do ALL of the steps needed, so that I get a fully functioning product that´s implemented on a website. Deadline: As soon as possible. Preferably right away. Background info: I sell online seminars about chocolate creation and production. I am using an online platform called Podia, and they work as a shop for my products (seminars). Podia is very basic, and doesn't offer any advanced coding, and I am pretty sure they don´t offer embedding of a calculator. So, to get around this issue, I am thinking of having a Wix webpage that will serve as a home for the calculator I want to create. What I have right now: Google Sheets with a database with approximately 400 products. Each product is categorized by main category and 2 sub-categories. For instance: Main category #1: Chocolate Types Subcategories: Brands of chocolates Sub-sub categories: Particular types of chocolate under each brand. Each single product (e.g. a particular chocolate type) consists of different ingredients (e.g. water, fat, sugar, etc) and these ingredients/components will have to be part of the underlying database. What I will need you help with: 1) Adding and categorizing a few additional products. 2) Fixing a couple of technical mistakes in the existing database Please note: • This database should be a source of information behind the calculator and should NOT be visible or accessible to a user. • The calculator part should be converted into an online calculator. Right now it has the following functionality: • Users can choose up to 25 products. • Every product must be easy to choose using categories and sub-categories. • When products are added to a calculator - the user can manually punch in how many grams of each product the user wants to have. • The calculator will display the amount of ingredients (e.g. water, fat, sugar, etc) according to the total amount of the products. • When all the products are added calculator displays - the total amount of each ingredient (e.g. water, fat, sugar, etc), and the total amount of products in the recipe. • Users should also be able to easily change the amount of ingredients (e.g. changing 1 kilo of fillings to 100g of fillings). IMPORTANT! The calculator should be available for multiple users at the same time without them interfering with each other or messing up each others calculations. Functionalities I want to add: • Option of easy printout/saving of the recipe. • Option to add notes to the recipe In conclusion: • I need someone who is skilled and has experience in creating something similar to my project. • I need someone who will understand that I have quite a complex calculator and I want this product to be ideally functioning and who will be able to advise and guide the process. • I need someone who will take care of the visual part of the calculator as well. • I am interested in working with someone who can do ALL of the steps described, so that I get a fully functioning product that´s implemented on a website. Let me know if this is something you are able to do, and if you are interested.
