TAT: 2 Days, even though I was not fast in responding
Result: A perfect CRM System [Perfex] - for Lead Generation, Employee Management, Customer Management, Sales, etc.
Let's go through the OP-Thread and Rate the Factors / Points mentioned:
This is about
Existing PHP script installation and setup to use the site
Where can we find the script?
You can choose a free or paid script. Just tell me what you need, and I'll find a match.
Let me know what you exactly looking for and I will search if there is any script available according to your needs.
Disclaimer: Sometimes it's hard to find the exact script (either paid or free) of your desired site. Please contact me before ordering, I will try to find you a script before ordering.
What else do you need to provide?
It would be best to have good hosting with no SSL issues and fast speeds worldwide. My Part, I provided him the Access to Hosting
If you already don’t have one, I can recommend one. Was not necessary in my case
And, of course, you need a domain. If you are confused about the domain, I can do the domain research and suggest you accordingly I used my main Domain, and he still gave ideas related to creating a subfolder for brand identity or better go with a separate page, link it 
So what exactly you’re getting, or the steps
I will install a PHP script on your hosting If you already have a PHP website script(which you bought or found online for free). Double written, but yes, he did 
I also can look for a script suitable for your desired site. Double written, but yes, he did 
I will set up the logo and description and replace all the brand names. He did not ask for it, but I think because I already provided him with everything and the Logo and everything was branded - maybe it could be better to take into consideration that the CRM could have a slightly different Logo
I will research the domain name for your site(If you require it). As I said, branded Domain already still gave me an option that there are other ways to do that 
I will suggest a suitable hosting for your site(if you already don't have one) Not necessary in my case.
Per installation and site setup, only $30 Pretty cheap! For what he did after implementation, the "Free GPL" downloaded, especially the modus, was not working because they were sometimes broken or had a dependency. For example,, I will install Zapier later; he offered his help directly help. 
One site installation is $30; you can order as many as you want, but discuss with me first offered me to install the Zapier Plugins for a discounted price, even though he said that no coding, he did + customized as advertised |
Overall: Price / Result Evaluation: 9/10 - This is on my rating scale beyond what I expected. I rarely give 10/10 Ratings, possibly for high-priced offers that go far beyond what I have requested.
But you can see this Rating of 9/10 as a perfect one, A++
We already have a next project in Place

Thanks for the Review Copy!
I can't wait for the subsequent implementation, three left
Best,
