URGENT Fix email glitch in .asp real estate website

I have a glitch in my .asp real estate website. Next to customer logos (this is a complicated site with many mini script set up so realtors can change their own listings etc), it displays the actual customer email addresses. However when one clicks on those emails rather then opening up an email program to email, or going to a form, it goes to a page that says page not found... I need someone to fix this asap. This site was created in .asp, the older .asp. So I need an expert please. I'd like to work with an individual not a company please. For someone that knows .asp there might be other work in the future on this site.
