How long would it take me to become confident speaking English with clients?

Hi everyone,

My goal is to speak confidently with clients and business owners in English.

Current level:

• B2 English
• 100–115 Duolingo score
• Very good grammar
• Good reading and writing

My main problem is speaking. Sometimes I know what I want to say but can't say it quickly, and sometimes my pronunciation isn't good.

If I practice 2 hours per day, how long do you think it will take me to become comfortable speaking with clients?

Also, could you share a 30-day speaking plan (2h/day) that would help me improve as fast as possible?

Thanks!
