Why a Security Catalog?

So basically why would anyone bother with a catalog? All we need to do is head to your online Yellow-pages or E-guide or something along those lines. All you get is contact info and maybe their location. That's about it. As an event organizer/planner, you're not going to waste time calling up the 150+ companies just to ask if they do event security or to e-mail all of them for a quotation.

So your next likely step as an event organizer would be GeBiz, Put up a Tender for your event and wait to see what kind of response you get. But as an event organizer, how do you assess the quality of the people who have responded and their expertise? Aside from what they give you, not much else. Not all the agencies will respond, this could include some of the better agencies.
They might have sufficient contacts that they do not actively seek out business, they could wait for business to come to them...

The other path they could take is by re-hiring a previous security agency they've worked with before. Doesn't really ensure much though. The company could be less than optimal for them but who else can they turn to?

So as an event organizer, we could potentially be left with a bunch of agencies that don't exactly meet your needs... Plausible enough, i say...

What if these event organizers suddenly had a resource they could search through? Read up about some companies that could meet their needs? The catalog could include things like past events, costs, company profile and their areas of expertise.
Suppose they required bodyguards for their VIP? They can filter the list down to which companies do VIP bodyguarding/escorting, read up a little and have a better idea of what they want? Then e-mail these companies for a quotation?
