Yeah like scott said ring around, have a look in the yellow pages and ring some of the big plastering companys or try some of the interior companys that do plaster boarding and ceiling fixing they are always a good shout, usually small builder do there own work so are not on the big ccomercial sites, but usually if you speak to some of the reputable companys they might have some work available, or they might even know of another company that are looking for spreads, its all about putting your self out there and letting people know you need work.
