Depending on the exact nature of the relationship between you and the person or organization you are doing this testing for, they may well be able to assist you; the organization you are assisting can employ VAR licenses for Ghost; these are used by computer manufacturers to deploy machines and also allows them to build recovery images and bundle a restore-only version of the Ghost cloning executable which allows that image to be redeployed to the same hardware. Since VAR licenses explicitly are designed for resellers, they don't have the same prohibition on sublicensing that the normal licenses do.
[ I'd note, by the way, that although sublicensing has been explicitly forbidden by the normal EULA, in practice it's something that is not uncommon; companies that perform outsource IT services sometimes purchase tools like Ghost Solution Suite on their own account, to be used on the machines owned by (thus, in effect on behalf of) the companies they are contracted with. In essence, as long as all the client machines which Ghost is used with can be traced to a license, it's mostly a case of "no harm, no foul"; Symantec's main interest in sublicensing derives from it being used to aggregate purchases to achieve bigger volume discounts. But as Symantec isn't being denied the license revenue it's due if things were done strictly by the book, no-one really cares. ]
Depending on the identity of the organization you are working with, they may already use VAR licenses but if not they are extremely inexpensive.
We were using Ghost server before but now we dont have license for that
Just to be clear, Ghost is not and has never been licensed on the basis of servers; Ghost instead is licensed on the basis of clients to which an image is deployed/from which one is taken. If you have a client license for some particular version of Ghost, then any and all of the tools in the edition of the suite being licensed - including the various server components as well as boot disks and what have you - can be employed with that client machine. Essentially, everything in the suite is an adjunct to the client license; even if it's not code that is run on the client, it exists to aid the client deployment.
For a machine to have a .GHO deployed to it, via any method, that machine must have a suitable client license and that license stays attached to that machine until it is (in the specific term used in the EULA) "put beyond use", which in practice means that the deployed image is erased from the machine via some method such as a disk wipe (at which point the license can be reassigned to a different piece of client hardware).
The license that is attached to a client to permit use of Ghost with it is perpetual and does not expire, until it is removed as I describe above.
