Can anyone recommend a company for a Facebook campaign?

Can anyone recommend a company/or had dealings with someone who specifically targets Facebook campaigns. Looking for someone to start asap.



Also be interested on people's feedback who've used something similar in there organisation, what were the positives/negatives? was it beneficial?



I work for a payment provider (Chip & Pin) and we're looking to raise awareness via social media, & target SME's etc.



Thank you
