Credit Score Management

Any thought how much it costs to have a credit repair company try and fix your credit report

I’ve applied in the past like a few years back for various dept. stores and was denied. Ive since quit applying for them and my credit score has risen as well. My credit score is better now in the mid 6’s. What are my chances of getting a credit card with anyone. Ive never had a credit card before can i get one now with my credit score?Who, why, what , when and where?
