Hey there welcome to the Myfico fam, being that your Bk is so new and you only have 3 mths of Payment history the chances of getting a larger CL right now with your scores is gonna be pretty slim , you could try Disco if you did not burn them ? Are you a member of a CU ?
Capital one is a good place to start. You should be eligible for an increase soon with them although you can't get another card for another 3 months. Try to stay away from cards from Annual fees or those that don't graduate to unsecured.
