Diamond Wire and Machine wanted for limestone quarry

We  have a small quarry in the united kingdom.  We are looking to extract stone using a wire saw (BENETTI ALPHA 840) Or do you have a similar machine and how much would it be ?

The stone we are cutting is a Permian Limestone, the stone is in the same seam as the 
The John smiths quarry in , Yorkshire UK and the  quarry in , West Yorkshire UK

Would you be able to recommend a wire for us and give an idea on the wear rate of the wire when used in Limestone.

Also could you give us a price on the wire per metre ?

Do have different specs of wires ?

Price to deliver to the and do you have a minimum order ?

We have tried many ways of trying to extract the stone and we feel the wire saw is the best way.  But we are unsure of the wear rates. We are looking at the process to be as cost effective as possible and hopefully with your product we can achieve this.
