Exp. Coders (min 6 hrs /day) in PHP/MYSQL/HTML/JS/CSS - handle programming tasks

We are looking for 2-3 independend experienced coders with at least *6* hours of work time a day (more is better) to handle specific tasks to upgrade/complete parts of an existing system (frontend and/or backend). These tasks require more than basic PHP coding, but require much data handling, MySQL select/insert, and Javascript/HTML/CSS. A lot of times, you will be required to look at existing code to build on it. If you are experienced, it will be quick to pick up. *** Don’t bother to bid if you cannot look at code and understand what it is doing, as you will waste your time on something you can’t complete, effectively do. *** You don't have to know how all the languages listed, but you do have to be strong in at least one of the following: backend coding (PHP+MYSQL) or frontend coding (PHP+MySQL+HTML+CSS+JS). *The payment will be clearly based on tasks and your ability to accomplish them*. Payment is based on milestones and their value. The range of payment (depending on your ability to complete tasks) could be anywhere from $250-$1000USD or more and will be paid as milestones (project will grow beyond the agreed initial bid, if can complete tasks). We are really looking for good programmers as if you can prove your worth, we will also be able to give you more work and pay, based on your skills. *** Requirements of the coder (Heavy on PHP/MySQL, lighter on HTML/Javascript/CSS) *** 1. At least 6 hours a day of programming time, the more you can accomplish, the more you will get paid. 2. Excellent knowledge of PHP and all types of data manipulation (strong string manipulation, file handling such as upload, file directory) 3. Excellent knowledge of MySQL with PHP (SELECT, UPDATE, INSERT, etc), you will be using Prepared Statements for data storage and retrieval 4. Excellent knowledge of Javascript (data manipulation for display or POST/GET) 5. Understand and can use AJAX (for asynchronous communication with server) 6. HTML/HTML5/CSS2/CSS3 (Website design) 7. Write simple but clear outlines of how you will solve tasks on paper, before implementing (showing us you really know what you are doing) *** You will be dealing with one of the following systems (and/or others) *** 1. eBook system (PHP/MySQL/Javascript) -- upgrading/completion of the following: a) ingest system (MySQL/PHP) b) user display (HTML5/CSS with some PHP/MySQL) 2. Badge system for eLearning system -- Upgrading existing tools a) upgrade the file uploader and file handling system (PHP/MySQL) b) work on badge display with user system (PHP/MySQL/HTML) We have done several small jobs on Freelancer to test waters and now we are starting to give bigger projects to freelancers, but with us, you will have specific tasks to complete, which should be done well, as every piece of code will be checked/reviewed by me. Therefore, once again, if you are an experienced coder, this is maybe a good job for you. As we work, we will open more jobs for you to complete. If you are interested PM and tell your details of 1. Your experience with PHP/MySQL/Javascript/HTML/etc 2. Your experience and what you are capable of 3. amount of time per day you can work (please don't waste your time bidding if you can't work on the project). Potential Bidders will be asked to answer programming questions (maybe skeleton code, or concepts) which directly relate to the tasks we must have done. Job is available immediately.
