if you been used to private mate now is the wrong time to get into site work, rates are half what they were in 2007 and it will be a tough transition doing three times as much work per day to earn the same crust.
but otherwise if your fast anyway and an early starter just ring any drylining firm and see if they have a start for yer simple as that really, only snag is they wont want you just nippin off for a week here and a week there to do your own stuff, they will want you there every day for the duration of the site so maybe have to do your private at weekends.
in manchester there are more spreads than jobs on site so good luck but there are alot of firms to try
