Good answers below. At one time I had 2resumes, each with a different interest, that broadens the field. Next, in front of a mirror or with friends practice /practice and more practice your opening presentation. Start with small clients first, don’t blow the bigger accounts by not being ready. It does NOT hurt to tell a client you are new and you appreciate their patience, most business people understand and will help with that. Many of them have walked in your shoes. Good Luck and PRACTISE.
