Good manners and a positive attitude in a social arena will open plenty of doors.In addition, here are a few simple ways any lawyer can maintain and build their referral network from $ to $$$$.$ - Thank you cards & holiday cards: At $5 each plus a stamp and 15 minutes of your time, everyone likes to receive a thank you note and a holiday card.Tip: Create your own company cards with rotating quotes for advocacy and inspiration (Hint: Notorious RBG) - these will stick around the office longer.Tip x2: Send a Thanksgiving card. 100% American + no holiday religious considerations, and you are the first card in the office and stay on the shelf for at least 30 days.$ - Setup a MailChimp Account and Send Out Tips, Pointers, Etc: Mailchimp and e-newsletters are easier than ever to create and send. They cost $15 a month, have near zero technical setup, and loads of great templates can be used.The substance for what you send can and should vary based on expertise, for example:Trial/litigation tactics - youu2019ll need the experience to be credible, but can break out sections and topics. 12 Section, with 4 installments or if you can create enough 42u201350 WEEKS of topics. Its easier than it sounds and you can and should reuse. I repeat, reuse previous topics, it will help you to see metrics on who is most interested in your topics!$$ - Host a Tasting: Have an interest in wine, whiskey, or know how to smoke fish or pork? Really, it doesnu2019t matter, just as long as its good and free people will come. You do not need to be a sommelier, hundreds of these exist in your city already. Find someone you like and as most are personable and present well (plus often have knowledge of whiskey, etc.) you can host a great tasting for under $750.Keep the event exclusive, inviting key people and those who are making recent and relevant accomplishments. Host your friends some other time.Tip: Want to pour the really good stuff but would prefer to share some cost, offer a trusted legal vendor to sponsor the event. Boom, out comes the Van Winkle!$$ - Send a Gift Basket: Sure, this has been done, but if you have someone particular in mind find out what they really appreciate. Get that rare Napa blend, Top Golf gift certificate, cash out a few Amex points, and put together the mother of all gift baskets. Make sure there are enough goodies to share so the team and support staff remember you.Tip: Is there a particular rockstar at the office who helps you execute and you know she/he is a contributor to the organization? Set aside a small note or gift with the name of the individual. Others will see it which gives the rockstar recognition and that will go as far as the gift.$$$ - Hamilton and High-End Events: Is a great show coming to town? The local Zoo hosting an adults-only black-tie evening of local fare and endangered species fundraising?Golf or tennis event, or Rolling Stones final tour? Get a group of tickets, well, you get the idea.Legal Conference Tip: If you may know everyone is going to Vegas for a conference, take everyone to a great show or out to drive a Ferrari at the motor speedway.$$$$ - Imagination Required: If the referrals are consistent and the relationship feels like a u201cretreatu201d would not be overblown, choose a destination easy enough to get to and arrange the accommodation, flights, etc. Cabo, Vail, Torch Lake, Sedona, and Kiawah Island can be easy enough to get to depending on your location.If anyone has a suggestion on how to improve please leave a comment (or create a better answer) and letu2019s build a great list!
