Hi,
Would you like only redesign or also change functions, add some modules? Which one? What do you mean "build in better social functionality", do you have sketches or wires to describe it?
I sent both websites to our designer, he'll review it and provide suggestions regarding best technology options on Monday till 4pm GMT.
So, please ping me a message for quick communications, it helps to send you a quote.
Happy Friday,
Vera
