Marshalls clay cobble setts. - Laying curved garden path.

[Lyme77]

I want to construct a garden path about 35m long using Marshals Ashbourne Red Muti, clay cobble setts, with an edging of Tegula Deco block paving.Never used cobbles before but really like the look of them !.The path is a continuous curve, so I think these would be ideal to use.
I plan to use a hardcore base of 'Crusher Run', 50mm deep.Cement the edging on to this next , then infill with sharp sand about 90mm deep, putting the cobbles on top of the sand, about 14 cobbles wide.Does this seem reasonable ?.
I also want to get the best price for purchasing the Marshalls cobbles/edging as I need rather a lot !, but don't seem to be able to find a building merchant that has these near me ?.Can anyone recommend a good reasonably priced source near to Lyme Regis in Dorset ?.

personally I would opt for 100mm subbase wacked
then 35-40 mm of grit sand
the edgings really need to be concreted onto the sub grade not the subbase
in fact for a path I would probably knock the bedding up in the mixer 6:1 and bed the cobbles on to that
90 mm of sand is way too much
you need to contact your local BMs or marshalls direct ,but for 35m of stuff its hardly a bulk order
good luck

No BM is going to keep these in stock, they will be ordered in as required.
