useing droid for online marketing

[CarisUniqueDesigns]

Alright, so I've got this crafting business & I'm interesting in learning about using social media sites for advertising. I heard hootsuite is good for connecting to multiple platforms but it costs $9 a month to be able to create pre-made posts on a timer. Are there any multiple social media managers that can do this, for free/less?
What else does the droid hold to use to create business? I have a facebook page & plan on using etsy & storeenvy...tips would be greatly loved!
