Logo and Social Media Design Required

Hello,

I require the following to be designed:

New logo for business.

Social Media Design for twitter, instagram, linkedin and facebook - to include header designs (same for each site) and also profile photo which will be designed (same for each site)

So a total of 3 designs to be done, but given in a format to work on the sizing guidlines of these sites.

I have a range of ideas, an existing logo but need someone to put the finish to the design for me.

I am looking for a strong designer, who can make something flat and simple.
