Add product customization and Offline char feature

Hello Guys,

We have a website with WCFM marketplace plugin integrated and are interested if there is a way around the below topics:

1. From the store manager, when a vendor adds a product, is it possible to keep the page as simple as possible? i.e He should be able to enter product title, description, images and shipping time only. In short, how to customize add product page (remove items)?
2. At the moment, ‘Ask a question’ feature works at the product level. we would like to have similar for orders as well. Once the customer orders an item, he might have queries on the same and we would like make it possible for customer and vendor communication or vice versa.
3. We are into clothing business and would like to allow our customers to customize their dresses, in this regard is there a plugin or an option to allow customer to enter measurements and select designs? In short, we are looking for similar plugin as ‘tailors online’ available with woo-commerce.

Regards
