"The simulators are a stones through from our offices"
Do you perhaps mean that:
"The simulators are a stone's throw from our offices"?
When you are trying to advertise a product on pprune it is absolutely essential that you first of all get a complete grip of the aberrant apostrophe and also get your spelling right otherwise nobody is going to take you seriously.
I certainly would not part with any money on the basis of your opener.
Apart from anything, I thought it was infra dig to advertise one's (note the apostrophe) services on pprune?
