The best way is to try freelancing jobs but it depends on what skill you have/What you can do.
Here are some sites you can try, They pay bitcoin.
1. https://www.xbtfreelancer.com
2). /r/Jobs4bitcoin (Reddit)
3). https://coinality.com
Or you can try on upwork or fiverr. They also have simple jobs.
Some advice, Your two hours a day is not enough to make a 1 bitcoin in just 2-3 months.
It is much better to just focus on your job than freelancing on some sites. Because you can just buy some bitcoins using your salary and keep it for investment.
By freelance jobs or selling services someone might earn some bitcoins with the time but as OP mentioned that he can just dedicate 2 hours of his time for that then it is probably not possible for him, and by that he seems to be looking for quick money or he might think earning bitcoins is easy which is not true.
