Send messages on LinkedIn (data entry)

Hi, I manage a LinkedIn account for a client who has over 3,500 connections. They would like to promote a conference by direct messaging all their contacts.

If you know LinkedIn, you'll know you can only message 30 people at a time. For this reason I would like to hire someone to do this for me.

The job is urgent and needs to be completed today or tomorrow. The content of the message will be provided, so this is just a case of selecting recipients and cutting and pasting the message.

Please do not send me a proposal unless you are sure you can get this done.

Thanks.
