One of my clients who has just started a business said she was antsy just waiting for the phone to ring. My reply? What can you spend your time doing now (while you are not swamped) to make that phone ring?

Some ideas to start relationship building that will keep you and your business in front of others, and therefore "top of mind":

1. Create or join a networking group that includes other professionals with whom you hope to do business.
2. Be a resource. Start or beef up your personal research and library relating to how you can provide helpful information, tools or tips to your clients or potential clients and/or any possible referral sources. These could include business or personal problems and issues. As you learn new things, share with others and get them thinking of you as a resource in  your field.
3. Write notes or send a branded (useful/memorable) gift to recognize milestones, news, events,etc. 
4. Clip news articles or magazine articles that are relevant and send to the person who is quoted or featured, or about a related business of interest, or anything else that is of interest to your prospective client or referral source, and include a short, personal note.
5. Ask for their input or help on a presentation or to give feedback on an article you're writing. People really like to feel important and needed, and will likely remember you.
6. Create or plan and coordinate an outing or an event, and all the better if it is work related somehow. Invite those who you want to do business with or who you would like to know better as a referral source. This can also serve as the beginning of a networking group if you really put your mind to it.
7. Send some "personal PR" about what you have done (like starting your new business) or a feat accomplished (like obtaining licensure in a particularly difficult state), or an article you have published or an article of interest that allows you to point out how it might help their business.
8. Volunteer for a group or an event that will either effectively demonstrate your skills in your business or place you with others who you want to know better.
9. Just keep in touch by phone or email so you are not out of sight and out of mind.
10. Entertain them: Lunch, dinner, golf or any other event. But invite and enjoy getting to know those with whom you want to do business.

These should keep you from just sitting and waiting for the phone to ring.
