How do I get more club gigs? Most of my dj gigs are weddings and birthdays

I've been djing for 4year and last few years has been alot of weddings and birthdays but i want to move more into club events. Done quite a few when I first started out but the more wedding and birthday gigs I do the more I get. I like doing them usually a good craic but want to start djing properly now I've built up experience and my confidence
