Well obviously someone has done it cheaper.
£5000 is a fair price but we all know commercial is cut throat business.
Would I have done it less than £83p psm definatley if I wanted or needed the work. - try £60p
You have to way it all up, if you get your foot in the door there may be a chance for more work at a later date.
Bills have to be paid.
I would just like to add, I think are gone the days where you can keep pricing up work to cover for weeks ahead.
We are in a resession, we can all say I wont get out of bed for any less than £££ but i think if that is your attitued you will be out of business sooner rather than later.
