business visa at Luohu

Hi,

I want to go to shenzhen to check some products, do quality control.
I have gone before and got the shenzhen visa.
The problem is after I also need visit a supplier in Donguan and Guanzghou. So I need the regular business or tourist visa to be able to leave the economic zone.

Can I get it at LUohu border crossing?

What would I need?
