I phoned the guy, he told me he was interested in having a website made for his company, but he wasn't able to go for it for a few weeks. I told him I understood and asked him for the name of his company, he told me and I checked the domain name availability. It was available and I told the client so, I then told him that the domain could be bought at any time and he may miss out on it.
The client then told me to go ahead and register it for him, I told him I would but I would need a deposit. That was a few minutes ago, I now have a 50% payment in my PayPal.
Hope that helps someone.
Nothing like waking up and making $250
