English heating engineer in Marche

HelloOur house needs a new boiler for central heating (LPG). We would like to be able to have some discussions and gain an idea of costings with an engineer as there are some aspects of our current system which we have never been happy with. Does anyone know of an English engineer living and working in Marche? We feel very limited by our grip on the Italian language and feel concerned that we could spend a large sum of money on something that is not quite what we were hoping for.Thanks
