I use a script called observium (observium.org)
I would like an instant search feature, very similar to whmcs, that will search the observium databases that I can put in the header to make finding things quicker.
I will not use escrow. You can install observium free, and test whmcs.
Create a working example I can test and I will paypal payment and you can send me the script to integrate into my site. This is a big internal site so I can’t get you access.
