Paypal "referenced transactions" buttons added to my Weebly website.

Please read fully prior to bidding. Weebly does not offer Coding or cpanel access to add Paypal API functions to my website. I have tried other alternatives to adding Paypal subscription , chained payments via plugin services like ( EZchain ). The problem I am having is my monthly subscription amount is above the max paypal allows per subscription period. Paypal only offers a Max of $2000 with subscriptions and my monthly would be 495.00 monthly thus only giving a max 4 month subscription vs. the standard and preferred 12 month I would like my customers to subscribe to. After working with multiple developers and communicating with Paypal, Paypal developer team suggested I should use "reference transactions" as a solution to this problem. So here is what I am needing to be completed... 1. I need to be able accept payments for two different subscription levels, example: I will offer a 12 month subscription for $495 and $295 monthly or pound Sterling equivalents 2. I need to be able to accept US funds and Pound Sterlings. Four buttons or two drop downs with currency option? 3. I need to pay my sales associate a percentage of the sales via a "chained payment" when a UK ( Pound Sterling ) payment is made. 4. It needs to work with equivalent, so it will need to be a plugin, HTML posted into a payment button on the Weebly site. If you don't understand Weebly and what you can and cant do, please don't bid.. ( I have wasted three weeks on developers bidding without the skill set or knowledge necessary ). I don't want to waste your time or mine. 5. Open to solutions or services that offer these requirements on Weebly. * check out and research Weebly options prior to bidding!!
