Hi. This sounds like a fun niche!! There are many was in which you could do this. You may want to think of it from several perspectives. I like the idea below of a directory of local party companies etc. Another thought is bday parties for kids - always a big topic with families, bridal & baby showers, party planning for weddings, etc. There are so many options. I think you should focus on what you enjoy the most. Best of luck!

I think it's a great idea! There are so many different things to do with it. People throw party's for everything!

where i am party shops are setting up everywhere I think its a great idea good luck cheers Helen

Great Niche! If you live in a big enough area I could see this as a good place to build credentials in a party planning business as well if you find you are interested in that kind of thing, or even local supply companies making a kind of directory. I imagine a lot of potential with "party planning" as a niche. :)
