some things that don’t work

good morning
I have to develop a crowdfunding platform for a customer.
I am testing your plugin on a test site.
there are some problems that limit it.
I spent a few hours trying to fix it. I also reinstalled the plugin, but I didn’t fix anything.

list:
– items that disappear in the back end (field and button to donate)
– the administrator does not have a short and long description to moderate the campaign.
– remove the shipping address
– the difference in the settings between your plugin and woocommerce is unclear.

when I have solved these problems I would have some settings to add.
I ask if you can do it by paying a reasonable fee.

thank you
