If you haven’t found anyone yet, I’m keen to find out more detail about your requirements (not completely clear yet) and give you an estimate.
I was about to start some hacking on the lightslider plugin this weekend anyway, because there are a few things I don’t like about it. I know it reasonably well.
… but I see this uses slick slider now I look it up. It still doesn’t look too hard and if I had time I might even try doing that for you without expecting anything.
PM me or post more details in case someone else can do it. I would want to know what you’ve already tried doing.
