I have a website built on OpenCart and need to make some modifications. 1. Create a custom inquiry form in which people can also upload the required documents 2. I want to create a mandatory sign up/registration before people can add to cart or checkout. 2.1 The sign up has two types of account registration which are Retail Sign up/Business Sign up 3. I want to do portfolio pricing for each category of the customers. Each customer can be placed in a tier and based on that tier they will only see selected products and prices for that tier only. (Please note this is still work in process and I need to discuss this with the expert to know what is the best course of action) 4. I need to import my current POS system to open cart to be able to update new prices all the time. (I currently have a plugin in place but need to make this process more user friendly like import/export of a csv file to upload the prices all the time without any extra work) I will arrange a call with the potential candidate to discuss things further. Thank you for your time to completely read through the requirement.
