When I contacted this small establishing company (via a friend). I already had several quotes, I took a chance as I felt at ease by their business-like, polite and friendly manner (which do count and is sadly lacking nowadays).
All in One I found to be knowledgeable and their advice sound, they provided a solution to a problem I did not foresee. They were very clean and tidy in their working environment.
Altogether I found All in One to be reasonably priced, trustworthy, knowledgeable, hard working with a complete high standard like finish. I would recommend them gladly as your first call.
p.s. Have asked them already to come back again to do my garden this year.
