Integration payment gateway into Wordpress Invoicing

The following is needed integration of Mollie API into my Wordpress Invoicing system (sliced invoices). Invoicing system: My invoicing system is called Sliced Invoices and currently handles my invoices to customer including an payment provider called Stripe. This payment provider doesn't work for me so I want it to work with Mollie. Mollie is another payment provider which uses the following API: [login to view URL] Sliced Invoices: [login to view URL] All the code used is already in a module called stripe. What I would like is someone to rebuild those pages to use the Mollie API. Let me know your bid for this job. Since the code is largely there through the striped gateway this should be an easy job. You'll get access to the following: - FTP - Wordpress (Admin) These two should be enough to do the job. My budget for this job is $50. Please reply with APIMOLLIE to be eligible for this job is $50. for this job
