I will auto-tweet a different link each workday to your business or website for at least six months. If I have previously written about your business, I will set up an auto-tweet for that article for 6 months as well.
I have around 2,000 followers across two Twitter feeds. Many of these are authors, musicians, entrepreneurs and social media specialists as well as some major brands. I promise nothing spectacular, but I often find my links are retweeted (RT'd) to specialist lists based on the hashtags I use.
I also use RebelMouse in conjunction with Twitter, which brings in a whole new audience, as well as posting links regularly on my G+ feed.
I will provide screenshots or direct links to all social media mentions.
