Hi Dean,
Just some advice regarding the price of your work:
The usual going rate would be about 2.5 x the monthly value. However, if the work is very good maybe 3 or 3.5x at the most.
According to my calculations, your work is worth about £15 per hour
(5hrs a day for 3 days X 4 weeks = 60 hrs for £900
therefore £900/60hrs = £15 per hour)
This is okay, but a little below average for the south of England i'd say. I just bought some more work thats about £22 per hour for 3x its monthly value.
So I think you'd be pushing it to get more than £2500 for such work. But, hey if someone will pay more, good luck to you sir!
Silly
P.S. 9am to 2pm??!!! Call that a work day?!! you could get it all done in two 7.5 hr days if you tried!
