My Website Need Modification

I’ve just done this website, but it was not done perfectly. So, I need to do the following to it: 1- It has no OnPage SEO Work. 2- It loads slower than average. I need to make it faster. 3- I need to do some modification to the website itself. It has a Database, Entry Form, Control Panel … etc. You must know PHP and MySQL. I don’t know whether you want to modify the existing website, or re-design the whole thing from scratch. As long as you can keep the final cost under $200. Regarding Payment: As you can see, I’ve paid and was screwed. So, I’ll pay this time as follows: 1- You start the work ON YOUR server. 2- When I see the work development, and ONLY WHEN I SEE THAT, I’ll make the first payment. I have this VERY SINCERE REQUEST: If you cannot do such work, or: if you insist on advance payment, please please please pleeeeeeeeeeeeeeeeeeease: DO NOT BID. PS: I need this website to be perfect because I have 6 websites that’ll use the same Database. I can give them to you if you do it to my satisfaction.
