Evening all,,                                                                                                                                                                   I have looked at a job which involves me cleaning and sanding around 600 sq/m of block paving and 250 sq/m of tarmac.   I will be using my gx390 21l  with hopefully a surface cleaner if I can get it to work,  would normally price block paving at £3 sq/m  then tarmac at £2.5 when ive work this all out the price seems too high, how do I price up for such a large area its in a private estate.
