I completed wholesale inquiry functionality. Last time email sending was not working on it due to which I could not test it on this staging.
https://stg-sdtdip.elementor.cloud/wholesale-inquiry/ user can apply via this form and a request will be submitted with a pending registered user.
Admin need to approve business owner in order to work his account. 
Once user is approved bsuiness owner can login and purchase product from this page https://stg-sdtdip.elementor.cloud/wholesale-buy-products/
I created simple page with button and text . We can do design of page as you want.

Also I asked to give me access for google search console for redirects task.
