otherwise it scares Samantha off as I am just rambling on about my business and what it offers.
You make an excellent and important point – you want to talk more about Samantha and her biz (rather than your biz) on your blog as that will build trust; and when Samantha trusts you, the chance increases that she’ll email you to ask whether you can help her.
You can talk about your biz, but ideally more as an illustration of how you’ve tackled similar issues Samantha is struggling with.
My feeling for your business purpose is that you want to help Samantha manage her itty-bitty business so she can feel better about herself and her life.
I’m not sure “managing her itty-bitty business” is the right phrase as that’s probably not how she sees it. Perhaps more something like… help Samantha feel proud of side-business so she feels better about herself and her life.
Perhaps not quite there, but feels like it’s moving in the right direction? When you can capture your blog purpose in one sentence, then it really helps focus your writing.
Enchant readers. Woo customers. Win business.
