I lost all mine in Manchester and Bolton areas which brought in about £10k per year.
Worried about it for a week or so and picked £10k worth of work up within the month.
Looking back, it was the best thing that happened to me.
The attention to detail that i gave to them could not be bettered, and that has been proven because the windows on the flagship store in Manchester is a disgrace, f--- em.
Dont worry about it, just get stuck in to the work youve got and more will follow.
