Website modification and layout change with share tribe website

Hi, I essentially need a marketplace set up from start to finish using open source code and with PayPal integration. I'm looking to create a peer to peer marketplace for some used products (specific products to be discussed if selected for job). I'd like to use the Open Source Sharetribe platform for the work (it's developed using Ruby on Rails). It's already fully coded and has a small community and several forks on Github. Here is the source: [login to view URL] While the hosted version ([login to view URL]) already offers payment integration, the Open Source version does not. So, I WILL need payment integration with PayPal so that buyer will pay to us and we will pay to the seller. The code already allows for mobile responsiveness I believe but I'll just need to make sure its responsive to various screen sizes. You'll just need to tell me what services I need to give you access to or set up (ex. hosting, PayPal business account, MySQL database, Google Analytics, etc.) and I'll provide you with the login credentials, or data you need. I'll also provide the images, logos, favicons, etc. as well as a few small tweaks to the CSS. Mostly the layout, we would like to config it like Airbnb style I have some technology background, but don't want to be too involved in the technical side; just want it up and running and transitioned to me smoothly. You'll need AT LEAST the following skills or experience: -HTML/CSS -Ruby on Rails -JS/JQuery -MySQL -PayPal API -Facebook (specifically Facebook Connect) Here are a few examples of sites already using the platform: -[login to view URL] -[login to view URL] Again, the source code is already there, essentially I just need it hooked up to a payment processor (PayPal), hosted on my account, and the initial categories (for product sales) added, which I'll provide to you. Since it's open source and I'll be providing you with all the categories, logos, pictures, etc. I'm looking to get this done at the best possible value. If the job is done well and at the right price I'll also likely get the same done for another 2 projects the same (basically replicating this same project, except selling a different type of product) for you as well. *Please include the word SHARETRIBE in the title to know you've read this and your price in bid. Working on a small budget, but some room to negotiate. Thank you.
