Should Get Screen Printing Machinery? (locked)

Greetings!

The t-shirt sales of my store are going good. I am taking screen printing services from a nearby shop, but now, I am thinking to buy screen printing and drying equipment to enhance the profit margins. So, I am planning to buy screen printing units and dryers from here https://www.cheonet.com/ for my different fabric and vinyl stuff.

First of all, do you think Yantai Senxi is the right place to get screen printing units and dryers? Or should I consider any other vendor? If you are using any US-based unit then you can name those brands.

Do you think it will be a profitable venture? Secondly, do you think purchasing an electronic dryer and screen printing unit will be enough to conduct these operations, or would I need more items? Or assistance machinery?

I am waiting for your serious response.
