Wordpress Environment Implementation Into Existing Full-Site Script (Project already about half-done)

Hello, This is a bit of an unusual project, so please read through. I have an unfinished project that I'd like to see finished properly. It's about 50% done/working. It involves implementing a WordPress environment into an existing turnkey website script, which is a traffic exchange system like 2leep, mgid, zergnet, etc' (so if you're familiar with sites like these - the better)... What I originally wanted to achieve with that script (referring to the turnkey website script) working under WP environment; From original project description; *** 1. No changes needed to the script - hierarchy and structure should stay intact as well as the script's own database. 2. All pages (both static and dynamic) generated by the script will be cached and then served by a WP caching plugin. 3. Apply a WP security plugin to the pages of the script. 4. Make a single registration through WP that will automatically create the same user as a registered member in the site running the script. 5. Fixing as many code errors as will be possible. 6. Try to make the WP environment will be universal and update-proof, and allow for any plugin to work. *** What I'm asking you to do is to go through the work of the previous freelancer, and take it from there... One thing I can tell you is that he did a pretty good work on #5, so error fixing is pretty much not needed anymore, and the code is pretty cleaned up. #1 and #2 are also done, but require some fail-proof checking. #3 is done but I'd like to run some security test on it, so perhaps you can help me with that. #4 is broken and needs work. #6 requires some testing, but that's for later and is not an essential requirement of the project, so it'll be paid for as bonus upon successful completion. The previous freelancer basically put WP headers in the script's generated pages to run the WP environment, but I'm open to suggestions, if you've done something like that before and have some different experience in WP environment implementation... You will get the full script to work with only if you're awarded the project, so the estimates that you give here are flexible and I can definitely pay more to the chosen freelancer as extras when the project is completed, as I know that taking someone else's work to work on can be problematic. Also please reply with the word quasar if you bid or message me, so I know you read through.
