Scam

I just received an email from a professional interested in my LinkedIn Profile Optimization services. She was concerned about doing business over the Web. I can understand her online security concern. Here is her question and how I responded:

Hi Donna,

I really would like to have you optimize my LinkedIn profile but my only concern is the payment side. You have a really nice site and I would love, love if you could deliver. I am just concerned about scams. How could we work through that? I am scared to pay upfront.

Thanks,
Jessica
