hi there
well the thought and opinion would be,
its a good idea!!!!
now look, you must start to plan the fundamentals of your business,
marketing, sales, customer visits, the service you are going to provide.
i would be intereested to know your background prior to coming into this industry.
asking sweeping questions such as
how do i price?
and
how do i get new customers ?
generally doesnt attract the response that yu are looking for.
asking a focussed and targetted question will get a good answer.
what you have to remember is that most people havce worked extrememly hard to build their business, and whilst not willing to help, some maybe reluctant to openly divulge the secrets to their success.
in answer to your question
phone,post, email or in person
ALL OF THE ABOVE,
and a lot of it
West London is awash with service providers, work out what your USP is
why should jo bloggs estate agent give you their business, inastead of the next cleaning company.
then start selling your serice.
regards
martin
