This job is a simple install of vTiger on a sub-directory. The vTiger uninstall script must also be intalled. The directory is to be named letters and the db is also letters. The URL of the unsubscribe is to the .../letters/[url removed, login to view]
This should take no more than an hour, or so, for someone experienced in installing scripts like vTiger.
I will use an escrow payment system.
This job must be done quickly. Time is of the essence.
