What you can do instead of re-listing (which I'm not 100% sure I understand what you mean), is to just update the page with some fresh content. Maybe reword the headline. Try new pictures.

Ideally you want some new aspect that the readers will find valuable.

I've seen pages with nothing more than an automatic date stamp inserted into posts stay in a competitive spot for years, with no other changes.... and they weren't even in that business anymore!

Small changes, but make it visitor valuable, and google will see you've made changes eventually. Go to a social bookmark site and enter your page their for it to get crawled again quickly.
