Natural stone is likely to be much more expensive than standard coloured concrete or crushed stone blocks.
They will need some real skill to lay as they are not standard sizes and probably little in the way of right angled faces. Look at the costs and time for dry stone walling for which there is reasonable comparison.
If they are retaining possibly waterlogged mud and tree roots they will need proper footings - not just cemented to whatever happens to be there. Any decent builder will want to avoid wall failure in the event of persistent heavy rain.
Finally a comment which may also be appropriate. We have just moved house and have been employing building contractors (builders, plasterers, electricians, Kitchen fitters etc) over the last few months. Day rates are much higher than I anticipated, and their schedules are full.
Builders of proper stone walls may be in a similar position to quote premium rates for what may be 4-6 days work + materials.
