I like your question.
Here's what I think:
You should do both of it because every places for advertising is the right one!
Create your blog at Google's Blogger and publish it every day because Blogger is being visited by millions of people worldwide!
Create your website about SFI is also a great move and something that you must have. You're making your own business here and you need to have official website, so people will see you're serious about it.
Send those to your friends, family by email, put adds on Facebook, Twitter and other social media and you'll see results.
