Social Media as a Medium for Treasure Brokers

I don't have a ton of time in each day.  All the kids are in school together at the same time only from 11:15am to 2:30pm.  That's it!  I have the desire of a 60+ hour a week entrepreneur but the actual time allotted to a stay at home mom.  Somehow with this schedule I have been able to; have my own Corporate Gift company, Wolf Marketing http://www.wolfmarket.com/, have a shop downtown (previously Sunshine on Sutter - now Gracefully Vintage) http://www.shopgracefullyvintage.net/, and be a Stella & Dot stylist www.stelladot.com/611.  As well as participate in shows with my furniture and jewelry.

The funny thing is that for Mother's Day when my kids wrote down a description of their mommy, they said things like, "I like it when mommy cooks for me" or "I like it when mommy plays with me" or "mommy cleans the house".  Somehow with all the above that I do, my kids still see me in the traditional mother role  (funny because I don't cook, don't clean well, and haven't had a date with my husband yet this year) but somehow, I am doing it all.  Rather than jack-of-all-trade master-of-none.  I am a jack-of-all-trades master-of-illusion!

What does this all have to do with the title?  I need help.  I need to be as efficient as possible to communicate what I do to the right people.  There is so much out there with email, website, facebook, twitter, craigslist, eBay, etsy, blogs, blah, blah, blah.  I could spend every second trying to create and maintain all of it.  I want to know what's the most powerful way to get your message and product out but keep it totally simplified.  Is that blogging?  A website?  Selling on eBay or is Etsy better?  I don't want to do all of it but what I do, I want to do well.

Thoughts, suggestions, best practices?
