$$$ What social media strategy - Crowd source, bots or steady Fiverr?

I need a solid social media plan. Currently I have a FB page (40k likes). I also have a Tumblr bot which I am happy with.
However, I am confused since I want a good SM strategy. I have three options here:

1. Go for crowdsourcing with SocialADR or SocialSynd or IMautomator. They have a monthly fee. Not sure how well it works.
2. Buy gigs from Fiverr or services from this forum where people sell 1000's of likes, +1's, tweets etc. Downside being they don't look natural without actual visitors to the site.
3. Get bots for other networks. Downside is that there is no reliable G+ bot which is imp. to me.

I have considered mixing the three but I'm looking for stability. Any sound strategy will be thanked & repped. Thanks in advance.

Forget fiverr. Just use your facebook and tumblr to direct traffic to your site. You can also incorporate other social networks as well like pinterest and twitter with bots

I guess it depends on what you do, but I've seen bloggers archieve succes with implementing Google+ comments on post and even Google+ posts within their posts similar to what you can do with twitter.. Be active and reach out to profiles with lots of followers in your target niche
