Payment Plugin for Wordpress/Woocommerce

I need to get a payment plugin done for woocommerce/ wordpress platform. The API is available. Find the PDF file attached. I have recently had very bad experience with the same on freelancer. People bid for what they really cant. And they dont seem to mind how bad I need it. A bengali guy has already cheated me for 80USD. He did the plugin but not fixing bugs. Please dont bid if you cant do this and deliver it faster respecting my need. I really need to get to know good coders as I can give them my future projects too. A local company has developed this e-wallet named Genie and we need to integrate it to our ecommerce site. You may have done similar projects so please bid if you have previous experience. Testers or learners please dont bid. I also need a very fair rate as I have already lost money on this. The plugin should be my property after the development. Should I need updates and bug fixes, you should be able to help. Dont ask for prior payments, due payments will be released once we are done with bugs and tests. Give me your best rate. The files attached should be treated confidential. I am attaching the plugin someone developed in case it helps you start.
