The company that might want to lease a domain/mini site may already have a main company site and will use the generic or geo generic to advertise. It would just need all their details adding, customising to them and the ads removing.
So they won't feel that attached to it and feel they don't want to buy it as nothing has been produced or pushed by them for that domain (letterhead paper, email addresses etc). Plus it must be cheaper than local radio or news paper advertising surly and I was thinking more like £100 a month!
If you have a mini generic site on there like my
HullSecurity.co.uk and it's performing well for seaches like.
- * security firms in hull
- * hull security
- * 24/7 hull security
- * security hull
- * security companies in hull
The unique hits are increasing it must look shiny to companies in the specific area. I know i might have side stepped by adding mini sites but it must help in getting the domain rented out?

worth a thought and something i'm trying at the moment!
ADDED - £25 - £50 a month does seem more of a realistic amount as clients could get a site built for the 12 x £100 I mentioned above.
