Integrate Codecanyon scripts together, database integration

I have a website with two codecanyon scripts installed. The main website root has this classified script installed: [login to view URL] In a subdirectory I installed this script: [login to view URL] Both scripts have been installed into their own databases and seem to be working fine. There is a slight problem with the website calculator when calculating some websites but I want to address that later. Both scripts have their own member account systems and message systems, all seems to be working in order. The message and mailing systems are using one Godaddy SMTP for the domain. The two scripts I have installed need to be connected, I would like to integrate them into a certain flow. I would like it that when a user first comes to the site’s homepage with the classified script they can begin freely reading the posted domains and send direct messages directly from the ad. This already works fine. On the top main menu of the classifieds homepage I would like there to be a moderately prominent button saying something like “Post your domain now” that when clicked takes the user to the sell your domain page of the website worth calculator. On the calculator is where they would first create their account, and begin the process of checking their website in the calculator, to then later go through the verification process to prove the website is in fact their own. OK, this is where the work is needed: A connection between the two account systems of the two scripts. I want it that not just anyone can post a domain on the classified script, but have to go through the process of evaluating and proving it’s theirs first. So each and every classified post has to go through the evaluator first. When a user makes an evaluation I would like them to be prompted with the question if they would like to post the domain for sale in the listings. If they say no then they can manage it from there with the option to always post later, but when they say yes it will start the process of making the listing. The listing: The domain name will be the post title The description will be whatever the poster wants to put and they can still put images. In fact a lot of information from the website calculator, including user imputed data can be imported. I would like to have all the website stats from the calculator to be called into the listing for users to see. Google maps isn’t important but maybe a nice touch would be to make it smaller and put the whois location on it. A comment system finally at the bottom, I may use a script or use Livefyre commenting system. There are a lot of other little things that need to be done along the way but the biggest is what I’m describing here.
