Where can I get paid for virtual services I would like to know what websites can provide virtual products:
For example, if I want to learn short video clips, buy related text or video tutorial materials.
If I'm having problems writing Python programs and would like refer programming guidance.
If my computer appears breakdown, I need to ask someone to undertake remote technical maintenance through the network.
If I want to buy some math instruction videos for my junior high school kids.
What websites can provide these virtual products? There may be free materials on the Internet, but it is too troublesome to collect and sort out. I believe that buying paid products can save more time and be more efficient.
