I need a Wix professional who is familiar with Corvid and e-commerce

I need an e-commerce/pay page constructed in Wix: I already have the remainder of the site built, just need e commerce portion built now. I need someone well verse with Wix, Corvid and e-commerce integration with Braintree. E commerce page will need to include: basic payment info, including PayPal and credit card options One mandatory item upon first purchase, then card will be used for future uses of services. I need to have a calculator, to calculate quantity of items X price, plus sales tax. I will want to keep the card on file, so I can charge after future uses of services, similar to a subscription service. it's not really a subscription, as they may use the service 1x a week, maybe 5x a week or zero times a week. so it's not a monthly or yearly subscription. The credit cards will be charged weekly, so i need to be able to communicate with Braintree Vault to do so. We need to set it up where we have permission of buyer. I will need to have the ability to have user data and send receipts out once card is charged weekly. Let me know how much you would charge for this, and time frame needed.
