Yeah that is necessary , i guess that would be so informative , having a responsive website will take your biz to whole new level. With all the necessary information there it will be so easy and convenient for you and your customers , to search If your services available in their locality or to  book , or pay online through bitcoin for the services rendered..! I'm sure you must have given it thought , i don't understand whats holding you back to not to go ahead with a site.
and BTW its not Bombay its Mumbai now
