Business Listing Directory PHP

Calling All Advanced PHP programmers That know how to deal with MySQL injections and write Excellent bug free code! I need someone that can check and double check and is an expert! Here is the request: Hi, I need someone to fix a website. The concept of the website is to register a business, then a directory of businesses. The problem is, its not coded properly and there are some bugs and it acts slow. I had another programmer look at it before and he did a really crappy job with crap code. So it would be nice if someone can go in there and clean up the code OR if its easier just to re-do the whole section In the website there are a list of businesses, basically the businesses register then you can view their listing. When you view their listing it needs to look the same for all the businesses (log in the same place etc) They have 2 choices: Paid and Free listings. The paid listings should be more of a full page with added fields The free listing has less fields. You can then upgrade your listing. Basically I need a professional PHP programmer to fix the code because so that there can be no mySQL injections. I think the code is poorly written. some other functionality is that it creates the company of the day. Also the website is acting slow. And I believe it's because of the poorly written code. So I need someone to go in there and clean it up. I would like it to be written in nice clean code with div and css It needs to look a bit better. Just fix up the design so its nice and clean and even. I attached specific requirements below: ## Deliverables please read the attached detailed requirements please check out the website and everything is in the attached. If you are a beginner then please do not bid as the last programmer was a beginner and this is why the code looks messy!
