525880 Script modification

I have a script which i brought. i like to have some modifications done in it. here is the script. [login to view URL] these are the modifications i need. 1.) there are 3 files to edit the db info on this script. i like to make the 3rd file ([login to view URL]) to take the database info from [login to view URL] 2.) [login to view URL] take the site url from admin panel (not manually type the site url in the file. take it dynamically from mysql after saving from admin panel) 3.) add advertisement codes from admin panel and display them in pages. (same placess as [login to view URL]) 4.) add meta tags, meta keywords, meta description directly from admin panel.) 5) "next button" on rate page just like in [login to view URL] 6.) if possible SEO friendly URLS I need this fast as possible.
