<human>: Background: 

* I'm a recent college grad and recently started a job at 60k as an engineer.
 
* I had a car accident without health insurance and couldn't pay my medical bill for a year and now have low credit score (transunion 627 (chase freedom rejected me and provided this) and equifax 705 (from credit karma))
* The only credit card I had was Amazon card that I got about 2 years ago.

I've been looking to increase my credit lately so I decided to get a credit card. Chase freedom rejected me, so I went with Capital one platinum (had multiple mails chasing me telling me I was pre-approved). On the mail, it said I'd get 1.5k but when they ran it through yesterday, they gave me only 1k.

If what I've read through is correct, this is absurdly low. My utilization will be hitting up high percentage even with a small use. I'm thinking of getting another credit card so I can stay at low utilization. I've went over my expense for each month and I'll have about $2k to spend a month excluding monthly occurring bills and rent. What should I do?
