Facebook and Traffic to website

I am a new business and want to start off wit as many as possible real LIKES on facebook and Twitter followers I also need some web traffic sent to my new site so we may kick off right. I have been dealing with a huge cooperation and they want an arm and leg to get started. My web guy said to try this first and we may never need the big cooperations. The $50.00 is just the start we just need to see results so we may continue. If this works we will be a weekly contract hopefully for a very long time. Any assistance will greatly be appreciated.
