Finding the right place

Hi, I am after advice again.
I am currently trying to work out exactly what it would cost, if I went all out and aimed high rather than working from home and gradually working my way up to owning a premises. I dont mind if I have to rent or buy but I can't find anywhere that is suitable for what I want. I have considered buying land so that I can then construct exactly what I need but this will obviously be expensive. Does anyone know of any good sites to view land for purchase? I could work from a small industrial warehouse or something but I will need a private, secure yard, all that I have found that may be suitable have been communial yards.
To understand what I mean, I will explain.... My business will consist of dangerous dogs being under rehab on the property. I will need an office/consulting space and an indoor area for the dogs to sleep and be secure at night. I will also need some outdoor land such as a yard or field attched to ensure that the dogs have the room to play and socialise amongst themselves, however this MUST be fenced as I do not want to risk the safety of others, (I will board the fences too, to ensure anyone putting fingers in to pet the dogs can not get hurt).

Any advice or good places to look would be welcomed. At the moment this is the rut I have hit. I want the place to be right and so if I am unsuccessful in finding a property in the next few months I will work from home for a while and keep looking.
