That kind of change will probably take you a long time. Don't get duped into credit repair, most of these schemes are designed to rip you off.
Pay your bills, reduce debt, act responsibly, and your FICO will take care of itself. But it will probably take you 2-3 years, assuming you do not have a lot of debt.
Again, the credit repair business is a scam industry. Don't get involved with it. Everything you need to know about improving your credit score is on the Internet and is FREE.
