It's wearying but there is so much work out there at the mo and people paying silly money for shoddy efforts that even the muppets are overflowing with jobs
It certainly seems that no-one wants more work... which is surprising. I'd prefer to pay more to get my jobs done and not do everything DIY... but it seems it takes longer to get someone else to do anything than doing it yourself would take. It is very disappointing - though, I suppose, if I ignore the value of my time, I can do decent jobs very cheaply if I do them myself.
