Get the work you need in, and get rid of the ‘dross’ as you’re going.
To be fair, you’ll have a slightly different outlook on what you define as ‘dross’ whilst your expanding . Backpack jobs, slightly awkward jobs are still jobs. People that you struggle to get paid from, underpriced jobs turn into dross.
In the end, you need the work to employ. So getting rid of work (unless its really crap) makes no sense, surely the ‘refining’ part only happens once you have enough work?
(Also, do your price increases anyway; got nothing to do with whether your works ‘cream’ or not, if you think they need it then just do it)
