525076 MLM System Optimization

We would like a company to look at our entire existing mlm script. Generally the system is working fine but it has been developed by about 5 individuals over a period of 10 years and we need to structure things properly, comment all scripts, optimize the system and database and make things run faster with slight improvements. We want a company that can analyze the entire system and we will need a detailed plan and recommendations on what needs to be done and the time frame. We would also like to know whether we should change the script to operate in a framed network like Yii, CodeIgniter, etc. Once we are provided with this plan / report we will post another project to do the actual work. At the end of the project we would like a spec document setting out how the system functions, what each individual script does, the structure of the database, etc. In other words a system manual that anyone can access and read to see how the system operates or should operate. We preferably do not want to work with an individual freelancer as our experience has taught us that (not all but most of the time) individual freelancers work when they want, disappear when they want, say they are going to work or help and then they just go silent and are not available. We would rather prefer to work with a company where the coders will report to someone and act responsibly taking into account that we are a national company running a big database and many transactions daily. We will also have an external php coder who will check what is being done by your company and comment on your work and the quality thereof. We are interested in a long term business relationship and as a result we want to see your company portfolio and website with contact details. Please do not bid without this. Later we would also require the contact details of the owner and manager. Needless to say we need a company with extensive php and mysql capabilities and experience and preferably a company that has done mlm scripts before and can show it to us with demo access.
