Dave, I'll ask this question as someone who ran a successful business for a number of years and provided business training and marketing advice to various other small businesses.
Is it so important to build the brand around your own name?
I mean this as opposed to setting up a business with a more eye-catching name/more expansive "brand" that points to the services you provide, or more importantly, the problems you help your customers solve? Not only does "Dave Baker FS Ltd" not provide a great deal of room for expansion, it also doesn't do much to differentiate you from the myriad other John Smiths in the market. Putting personal recommendation to one side for a moment, what would motivate someone to call Dave Baker Financial Services rather than Richard Smithers Financial Services for instance?
My advice would be to think through the eyes of the consumer you're trying to attract. When they come looking for you, what are they searching for? If you don't mind me provoking you, they're not looking for Dave Baker (those who haven't been referred to you anyway). What they're really looking for is the answer to a problem, a way to understand something they don't understand, a better way to do something, etc.
When you look at Andy's business "Outstanding Branding", you already know what you're going to get and, if you're looking for some outstanding branding, you're perhaps more likely to place the call with his company than with any vanilla John Brown / Peter Smith Ltd.
I remember reading a book a number of years ago called
Purple Cow marketing which is all about, funnily enough, standing out from the herd and doing certain things to avoid just blending in. It's a bit cheesy and American but the message is pretty effective. How can you be remarkable and interesting? How can you draw attention to yourself in a world full of other cows?
If I'm being brutally honest (and you did ask for opinions - albeit for the logo), I think you're planning to become another "Me Too" in a "Me Too" industry. Having met you on a number of occasions, I think you can achieve far more than that.
