How many of y’all DJ for weddings? I’ve made a basic calculator that hopefully will help give a better idea on what a budget should be for different levels of DJs. You might be ok with a few hundred dollars, but usually, the client gets what they pay for. Check it out and let me know if you like it, or what I should improve.
Sorry for the super slow response. You can just link to it. Not really open source. I just made some estimates based on national numbers from sources like Wedding Report.
