I have an existing functional website which uses paypal it is based on this script with slight modifications. [url removed, login to view] it currently accepts payments through paypal and pays out through paypal.
I need to integrate a new payment solution see [url removed, login to view] for specifications.
the new payment solution is for purchases only and payout will still be done through paypal.
The site makes heavy use of smarty templates so experience of this would be an advantage.
Also I would like to keep the site up while this work is carried out.
please only bid if you have the relevant skillset and to prove you have read all the text before bidding what is 2 + 2
