Hello Thomas,
I can do the job for you. I have extensive experience working with standalone Q & A systems like this one as well as WordPress based ones to deliver a stackoverflow or stackexchange type of end product prior to this and can do an excellent job for you.
I have gone ahead and placed a bid now and we can get started any time you are ready to begin.
If you have any questions for me, please do not hesitate to let me know and I will get back to you asap.
Look forward to hearing from you and working with you.
Regards,
V
