Make a webshop

We need a small webshop designed and setup. The products will be made up of 5-8 main products with variants and custom selections. Some of the variants will have input fields for information to be added to the products and some will just be type(variant), widht and amount. Some of the products have variants that limit other variants, ex. If a customer choose Samkjøring(several orders will be produced together and giving the customer a discount) they will only be able to chose one amount and some will demand that they fill out the input fields. Input fields for all products that require it. Name, Title, Phonenumber, Web address and email. None of them will be required. Business cards: There will be 1 product with 6-7 varaints. They should get to chose from either a dropdown menu or a image button selection. There will be individuall pictures of each variants so when they choose a variant the picture of the one they choose is shown. When type is selected they get to fill out the input fields. After that they must choose between Samkjøring or rush. If they choose samkjøring they will get a discount on the price and they will be limited to 250 cards, there must also be a text line explaining that there need to be atleast 5 orders with samkjøring for production to start. After they choose samkjøring or not they get the option between 250-500-1000 cards, with price changes for each one. After that they can add it to cart. Rollups: 1 product with 3-4 types, two widths to choose between and amount. No input fields Flyers Several different variants, not determined amount yet. Some of the products will have inputfields, like if they choose samkjøring they get input fields, they will also be limited to only order 250 pcs, just like with the business cards. So the order flow will be the same, Select type, samkjøring, input fields and amount. Apperal This will be 4 different products, one will be a simple product and 3 will be products with variants. Tshirts, Pique shirts and jackets will have the same setup, so i will add the info here, but it will be 3 different products. There will be 2 color choices to choose between, amount, size and two different branding choices. They can choose between transferprint and embroidery, both should be buttons/pictures that they select from. The last product among those will be a simple product called Transfer print and will have no variants. Stickers 2 variants, both with input fields. Amount: 100, 200 or 300. There needs to be easy and quick to add new products or variants if needed. We also need to be able to remove variants if needed. Shipping will be fixed price. Payment will be through paypal.
