Advanced Search less than or equal to

Hi,

Is there some way to do a search on a custom field for all values less than, equal to, or great than X?

For example, I have a directory with 50 hotels in Denver. I’ve set up a custom field called hotel_price and given the following options:

Under $50/$,Under $100/$$,Under $200/$$$,Under $300/$$$$,$301 and Above/$$$$$

Then when searching, I’d like a dropdown with:
Under $50
Under $100
Under $200
Under $300
$301 and Above

It doesn’t have to be exactly like this. Whatever kind of syntax works really. The main thing is that the results need to include all options selected and below.

So if someone wants a list of all hotels under $100, the search should return those marked Under $50 and Under $100. I found the Advanced Search option that allows for a Check Field Data Type, but when doing a search it requires a user to click on the gear icon (which is an incredibly well hidden way of specifying search criteria and then check multiple boxes.

Any suggestions? Even something like the GD Popular Post widget would work, if I could populate it with links that give those “Under $___) options. I just need an easy way for people to filter out the expensive results.

Sidebar filters could do it to, like you might see in hotel booking sites that allow filtering on various criteria.

Thanks!
