I have a website which is "Professionals Directory". I have separate website for each professional. On the main "Professionals Directory"website, I like the visitor to be able to choose the right professional by three drop downs. For example the first dropdown will list the tyoe of profession. For example
Second dropdown will ask the visitor to enter his Zipcode, so that it will list the plumber or carpenter in his area of residence.
The third dropdown will be Language. Here the visitor will select the language spoken e.g. English, Chinese, Portugese etc. by the professional, so that a Chinese speaking customer can look for a tradesman who speaks the language.
