Exposed aggregate concrete finish

Hi
I am interested in getting my driveway done in an 'exposed agregate concrete finish' where the top suface has exposed decorative gravel. I like the benefit of added grip on my sloped driveway and appearance.
I have seen resin bonded dressing but prefer the exposed concrete option as believe more durable and economic for a unique finish compared to bitmac etc.
My question is I am having difficulty finding anyone who advertises doing this process? Is it a specialist operation or could any reputable concrete contractor undertake this as i understand experience and timing is critical for washing/exposing the agregate uniformly to get good finish?

Appreciate any info from people who are familar with this process and could advise on.
I am based in North West [Donegal/Derry area]

Thanks
