I need someone who can add drop in code from Braintree to an already developed Wix website

We are a rural internet provider and have just switched our payment processing to Braintree by PayPal. We did this because of several things they offer, but the main reason is we have recurring subscriptions with a first month add on equipment fee. Braintree has a perfect set-up that has allowed us to set up each plan we offer, with the equipment fee as an add on the first month, and then the equipment fee drops off and the subscription continues monthly. We need someone to get the codes Braintree already has and integrate them onto our Wix website. These codes will direct the customers directly to Braintree to pay and then send them back to our website after checkout, if needed, to say thanks. We will also be adding another website for tv and need payment codes there too. Again, the codes are already done on the Braintree website. I looked at them (I was looking at Java because I knew Wix would accept html codes - don’t laugh if that sounded dumb. I’m not a coder. Just trying to get my husbands website going.) We just need them copied from Braintree to Wix. According to Braintree, an experienced coder should be able to do this in about 30 mins or so. They have instant email support.
