We need a one page order form created that will then post a transaction to Authorize.net by the Server Integration Method (SIM) using PHP. The order form will have several rows of items which the user can select the quantity to buy. When the user changes the quantity, the total cost should be dynamically updated on the page (see attached PDF for form layout and function). We will use the Hosted Receipt option and will also need an email receipt sent to the customer. Line items (not just the total price) will need to be reported to the merchant so that we can package the orders correctly. The page will need to be able to function in a WordPress environment, but you will not be creating the page in WordPress.
Please see the attached PDF for the layout and functions needed on the order form. The very last word in that document should be the very first word of your response. Responses without the secret word will be deleted immediately. Please also tell us your experience with using Authorize.net SIM, PHP, and HTML. This is a small project, but we need it completed very quickly. If you cannot finish by the deadline, do not apply. We are a growing company and if you perform well there will be more work in the future.
