There are quite a few directories, like wedalert.com, that list upcoming bridal shows/expos. You could probably Google bridal shows houston tx to see what comes up.
I’m in the southeast GA/SC area & have only attended one bridal show in Atlanta. The booth reservation was $200 & the show sponsor provided a table, chairs & signage. I brought a monitor & a DVD player, along with copies of a preview video & a full wedding DVD to show brides that were coming in. I made sure to have plenty of business cards available, a couple of small signs that had info about our wedding packages & prices, & a planner to write down brides’ contact info & wedding dates.
This show was small, in a conference room at a hotel, & since there weren’t that many attendees, I was able to spend more time asking questions & telling them about our services. It was a good experience, but I didn’t book any weddings from it. Half the people there seemed to be price shopping, & the other half seemed to be there for the freebies (every vendor was required to hand out a door prize).
If you attend a bridal show & there’s a wedding consultant there, I would suggest talking to them. It’s a good idea to network with other vendors – if they know about your business & like you, they’d probably refer your services to someone they’re working with. You could possibly book some more weddings if you offer some kind of deal, like a free ceremony video or a discount if they book during a particular month. Getting the word out about your business is going to be the key thing.
