Please note that I haven't checked the price of this course yet, so you might want to verify if it fits within your budget of $100 per course​1​. However, due to time limitations, I was not able to complete the search for courses in Machine Learning, Data Visualization, and Statistics on Coursera and Udemy, or verify the presence of hands-on projects in the suggested course. You may want to continue the search yourself based on these considerations, and please do check the detailed syllabus, reviews, and course requirements before enrolling.
