Your notation is again unreadable in many cases (3, 4, 5, 6, 7, 9, 11, 12, 13, 15, 20) . I won't be answering this time, because I've had bad luck the last two times trying to helpyou, losing out to others and getting a lowered rating. Whoever does these for you will need a clearer set of questions.

Ask-a-doc Web sites: If you've got a quick question, you can try to get an answer from sites that say they have various specialists on hand to give quick answers... Justanswer.com.
...leave nothing to chance.
Traffic on JustAnswer rose 14 percent...and had nearly 400,000 page views in 30 days...inquiries related to stress, high blood pressure, drinking and heart pain jumped 33 percent.
Tory Johnson, GMA Workplace Contributor, discusses work-from-home jobs, such as JustAnswer in which verified Experts answer people’s questions.
I will tell you that...the things you have to go through to be an Expert are quite rigorous.
