Wanted: Domain Appraisal Appraisal: corporatewebhosting.co.uk plus a few others

[JagoHarry]

Hi All,

I'm still learning to understand the value of domains. I typically can tell when a domain has some value, I usually have trouble with just how much value. Could anyone help me with a value of the following please?

corporatewebhosting.co.uk (e.g. 1,560,000 results in google.co.uk, plenty of hosting adsense ads)
helprequired.co.uk
smsjoke.co.uk

(As a pair)
greenserver.co.uk
greenservers.co.uk

Thanks!
Dan
