The materials I always have at hand while I am out are my brochures and business cards. When I am at home I have a selection of questionnaires that I keep next to me for when a potential client calls.
The forms I always have at hand while at my desk are:
1.) Client intake form.
2.) Transcription Questionnaire
3.) Logo Questionnaire
4.) Website Questionnaire
5.) Bankruptcy Client intake form
6.) Real Estate client intake form
7.) Contracts (for all specific niches) a lot of clients that call want to go over my contract terms and policy.
8.) My handy dandy note book

for taking notes while speaking with them.
I have a nice little roll cart that sits next to my desk that holds all my forms. I like to go over with the client everything that I can so that nothing gets missed.
I find it easier if I can get the client on the phone to close the "sale". It comes naturally to me to talk to people over the phone and it also helps me understand their needs, wants and desires as well as if we are going to be a good fit or not.
