Multiple Facebook Messages Sent

Hi there. I require Freelancers to send messages to the inboxes of Facebook Business Pages in the UK which are searched under Facebook Places. The messages explain the services we can offer and we receive a 1% return rate of interested clients. I am offering the job of sending out these messages and to get paid for each positive result at $5 per interested response. For example, if you send out 100,000 messages, you will get 1000 positive responses which equals $5000 to the Freelancer. We have to do it this way as we have no way of checking how many messages you have sent out. This is a long term proposal for honest and hard working Freelancers. You need to either have multiple Facebook accounts or accounts with good standing which are allowed to send out high amounts of messages.
