There is no difference between buisiness J1 and private J1. US DOS and USCIS don't care if your J1 is buisiness status or private. When you submit your waiver application, you need send them all your J1 form copies. Please note you should ask for longer time J1 from your professor so that you have enough time to do your waiver. The time estimate for your waiver:

1) 6 months - submit to Chinese Embassy in US (you need at least 6 months stay in US before you have request waiver to Chinese Embassy in US)
2) 3 months or much longer for approval in China depends on you paticular situation
3) 3-6 months -- process in Chinese Embassy in US
4) 1-5 months in US Department of State (DOS)
5) 2-12 months in USCIS

Total: 15-22 months

I would suggest to aask for at least 3 years J1 (5 years total now). If you get waiver approved before your J1 is expired, you can continue to use your J1 and it's eligible for you to apply for your H1 or green card at the same time.

if you J1 is longer enough, you will not need H1. You can start to prepare for your green card application once you enter US. I-140 doesn't need J1 waiver approval, only I-485 need it.
