Scott L: From my own personal experience, I can definitely tell you that if you sing(while playing the kb), that it will greatly increase your gig earning potential ! Singing somehow commands & holds the listener's (audience) attention 'a lot' more than performing an instrumental set only. I strongly urge you to seriously consider investing time to develop your pipes (voice lessons?).

As far as rates go, first find out what the 'going rate' in your area is for people doing similar gigs (nursing homes, retirement communities, clubs, weddings, etc). Start your rates at the lower end of the spectrum to attract/build up clientele. If you aren't already established or known in your area, approach a suitable venue and offer to play for a first time intro rate (such as 1/2 of your normal rate), but do NOT play for free (even for the first time) to potential paying clients. I've found this technique usually doesn't work out. I reserve free playing only for legitimate non profit fund raising benefits & events and for family/friends. I recommend establishing and charging all similar type client venues the same rate because nothing is worse than one client finding out you charged more/less than the other guy. Consider rasing your rates only after you've established yourself in your area = your gig schedule is fully booked for a month, and you can afford to turn away work. Honestly, integrity, promptness, and an outgoing friendly attitude will bring you respect and subesequently bring more work and more $. After playing a potential ongoing venue a couple of times, I strongly recommend you sign a mutual business contract to protect both parties. I also insist on written & signed contracts and receiving a non refundable deposits for wedding, anniversary party & corporate gigs as well. I hope these suggestions help. I'm sure other pros out there (Uncle Dave, Donny, DonM, Mario, etc) will have other suggestions as well. Good luck.
