There are a lot of websites which teach online drawing lessons. Recently, the government has announced that it will pay for the fees of the online drawing lessons. So, you don't need to pay anything for studies except registration in these websites to start your studies.
Please see the websites in related links.
Good drawing scanners could be bought from a variety of sources, such as websites and stores. Some of the best places to buy them are from Colortrac, Best Buy, and Amazon.
