Way to search for people offering specific types of commissions

I know there's a place showing commissions and whatnot, but I think it would be really neat if, say, somebody was looking for badges for a con, they could specifically filter and find people who are open for that?

I'm unsure if this is a realistic option, but I know one issue I've had in the past looking through regular submission tags would be that 80 percent of posts are COMPLETED items. Filtering through that manually gets stressful. Like last night I went to the YCH tag and it was basically all completed YCH. Thats great, but not what I wanted to see.

Does this make sense at all? Basically a tab or something that exclusively showed people open for commissions, then a way to search it specifically for certain types.
