What's the best way to structure a google ads account with 4 separate campaigns covering 3 states? The 4 campaigns are for separate services: bathroom remodeling, kitchen remodeling, cabinet refacing and a brand campaign.

I've considered doing state based campaigns but it would make the account more difficult to manage because it would now be 12 campaigns. Would it be worth it? I can't combine the services into 1 campaign because each service has a separate budget. Thanks for the help!
