Just spent 99p too. Not a lover of pricing books at all... but for 99p it's worth a read and potentially a laugh.
Further to what I said earlier (typing on my phone and have fkd my right hand so it's not fun) The money is there for a sensible contractor with a brain to make a decent bit on a job. Times the actual landscaping is needed the area will be pretty flat with either a crane access or hopefully a access for a 2t machine up a slope or in via a path at the top of the site. What is not needed is the type of yes man wanker landscapers I have dealt with recently who will say they can do everything for nothing and then wind up charging a ridiculous amount of extras......

(I then usually am the mug asked to come and put things right

) The job is the type that needs someone with a brain, the client knows it won't be cheap but equally the budget is not a bottomless pit.
The Views are f****ng awesome! Right near the coast!
