Set up payment processing for marketplace

We are looking to hire a developer or team of developers to help us launch an online marketplace where products and services will be sold from professional contractors to homeowners. We are a tech startup based in Canada and we're looking to launch this new arm of our business. 95% of the website development is complete but we are now looking for a developer to help us finish what we started and get this launched. We have a few minor changes to make (roughly 3-5 hours of work) but more importantly, we need to implement a payment processor (PayPal Adaptive Payments). In our eyes, there isn't a lot that has to be done here to launch but the complexity of the project can be discussed further. The current wordpress site is built off the Marketica theme which was purchased and customized for our marketplace. Here is a link to the theme that was purchased.

[login to view URL] The biggest issues we are having right now have to do with the payment processing and ensuring that is working correctly and safely using PayPal Adaptive Payments. We need an easy way for our contractors (sellers) to be able to sign up, get their profile complete and payment information in here so they can start selling their products and services on our marketplace. Our first developer was setting it up with Stripe but he left before he finished. We then hired another team of developers to get this done and they were using PayPal Adaptive Payments (chained payments method). They are no longer responding to us so we are now forced to bring on another developer to get this done. We don't know how much was completed from these other developers but you will have to take a look once you access it. We are looking to hire in the next 24 hours in hopes of getting this marketplace launched in the next 2-3 days. We need to get this done asap! Further details will be provided to that developer(s) we hire for this project. Experience with Wordpress, WooCommerce and PayPal Adaptive Payments is a must. Any experience with marketplace multi-vendor e-commerce solutions would be highly sought after. We would be open to hiring the developer(s) to future work as well if we are successful with this project. Thanks for applying!
