They may have to pay. Circa £500-1000 is the norm day rate.
Any info on setup? Vanilla network? Windows version? Do they have all the paperwork for licensing etc?
Yea, that the sticking point, they don't have much money and certainly wont be able to pay that "going rate"
As for set up, i don't really know. I have asked my wife if i could go in and have a look and shes working on it but i do know its a mess.
There is no consistency with equipment or software, its as if their IT guy goes to PC world and just buys whats on offer that week.
I dont really have much info to be honest.
