Gravel drive help please - Best recipe for weed free drive

[Verytired]

Can anyone tell me what is the best way to sort out an old rutty weedy gravel drive - on a budget?

My questions are:

What depth of base, are road planings ok or is there a better option, what depth of gravel for light traffic, do I need a membrane down to stop weeds, what are the best edging materials - sleepers any good?

I suppose the question could be: what is the minimum spec for the least price without doing a rubbish job that won't last.

Also, is there any calculation of how much a square metre or yard etc a gravel drive might cost. Ours is very long!

Any replies very much appreciated. Apologies if topic has been done before.
