Starting welding business

#1
I have been working in the welding industry for 10 years. I am skilled in arc welding and stick welding techniques. I worked on a ship for 4 years. I have experience in working in different industries apart from welding. I am a certified welder. I am thinking about starting a business on my own. I want to start a fabrication shop. I have read that welding workshop is the best idea for small-scale investment. I hope it can be a solid business plan for highly skilled workers. Is it true that running a workshop through moderate commerce is an appropriate idea for beginners? Does it require a high degree of investment?
