Day parking permits

Our freeholder has sprung some works on us tomorrow and wanted to help the contractors as much as possible.  I only have a few 1 hour permits that I want to keep for essential trades.

I know there are machines nearby for this purpose but I said I would ask on here if anyone has any daily permits and how much would you want for them?  Or do you know of any streets in the area which offer a free 4 hour stretch or more for example?
