Fix bugs and setup some scripts in a PHP core website

Please do not bid on this project if you don’t have 5 stars for at least 30 reviews, or you charge more than $15/hour. I’m looking for a strong PHP developer to fix a few bugs in my website and setup some new scripts. I have an auction website which is cloned in three languages and each language is hosted in a different domain (English, Spanish, Greek). For your convenience all the 3 CMSs are in English. I want you first to fix the few bugs mentioned in the document within max 1-2 days in order to start operating in the market officially, and then to focus on the other 6 last points. Whatever you fix or add in the English website you will have to ‘copy-paste’ it in the other two websites as they are clones of each other. The requirements include: - Fix SMTP authentication for autoresponders. - Setup GA (+ e-commerce tracking, and task manager). - Setup PayPal IPN and change sandbox to a live gateway. - Setup new autoresponders and a manual payment script The three websites are: [login to view URL] [login to view URL] [login to view URL] How the website works: The website is an auction platform for students (customers). The customer uploads an order with his needs and then there are writers (sellers) that review the order and can place an offer on it (bid). Then the customer can get more information for each writer by checking their profile for more info and reviews from the past and at the same time chat with them through inbox. When the customer decides to work with someone in the website, he accepts the offer and gets transferred to the payment page to prepay for his order (we only use PayPal at the moment). Once the writer delivers the customer's order we release his payment by keeping our commission automatically. Thank you for your time :)
