No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I am no expert on BK, but you make to much for a 7 especially with your expense so that leaves you with a possible 13.. Obviously you don't need cable your cell bills can be cut down to less than a 100 a month, food can be cut down etc. Cars are fairly high payments as well if in trouble not sure how what you owe on those left, etc... alot of fat to be cut and can dig yourself out and as other mention uber or side jobs for you/wife. Best of luck.
I use mint to budget and track expenses.
