You better get your self registered with Placement Agencies, recruiting for reputed Banquettes and star Hotels. Being experienced bartender you shall not find difficult to switch over to job of your choice.

If I were you, I would get some business cards made up, and start going to wedding trade shows.
Set up a table and pass out your cards and put on your PR face.

Wedding bartenders keep busy and mostly work weekends and evenings. Tips are great too.

good luck

Try Hotels with banquet rooms, the better the hotel, the better they pay. I worked as a bartender/server for a four star hotel in PA for about two years, and I got hired with no experience in bartending. With a hotel, you get steadier work, and it usually pays better than independent catering companies, plus there are more hotels around.

Advertise yourself on Craigslist. Otherwise I’d think you’d have to work for a catering company or somebody that offers bartending services.
