Am i going about this the right way credit rebuilding wise? 10points?

My credit is really bad. i defaulted on student loans...and a credit card with a small balance on it due to bad hardships. i hired a company to repair my credit by trying to get negatives off my credit reports since i was nervous to do it myself. in 3 months im opening up a $2000 secured credit card through my bank hold it properly and manage it perfectly for a year to gain a unsecure one in hopes the high amount will give me a high amount unsecured one. in about 6 months im taking out a secured 1000 loan against a 1000cd purchase im going to do. will this raise my credit score significantly? please help. im new to all of this
