How much does it cost to invest in a basic business studio and what equipment to buy?

You didn't say which area you are from! So let's not talk about rent and employees!

As long as the equipment is complete, the camera and lens 1W depends on your personal financial resources! Nikon D90 and Canon 450D are both suitable for investing in businesses that are not particularly large, and the results are basically satisfactory! And lights! If you shoot people, a studio of about 50 square meters needs at least 4 lights! 7K or so to 1W plus lighting accessories is enough! Recommended brand Jinbei! Then there is the background and other small clothes! See individuals need to buy! ! Overall, about 3W!
