Payment Method at Checkout

Hello,
I have a question that relates to our WooCommerce store.
Our business sells two types of products: 1. Portable bars and 2. Kegs of beer.
Presently, all products in the store are listed as kegs of beer, whilst the portable bars are listed as variations. Firstly, customers will select their keg of beer. Secondly, customers will select their preferred portable bar to dispense the keg (Option 1: Corporate Bar, Option 2: Outdoor Bar, and Option 3: Own Bar – each priced accordingly).
The total cost is calculated as the sum of the portable bar/s + the keg/s.
Due to liquor licensing restrictions, we are unable to take payment for the kegs of beer online. The keg/s of beer need to be paid for as cash on delivery (COD).
The portable bar/s need to be paid for by PayPal or bank deposit at the time of booking.
I require a WooCommerce plugin that adjusts the amount payable based on these two product types.
The plugin would need to charge for the portable bar/s by PayPal or bank deposit and the keg/s by COD.
I require a WooCommerce extension that adjusts the amount payable at the checkout based on these conditions.
Would you happen to know of an existing plugin that meets these specifications or any advice on how I might be able to resolve this issue?
Any advice would be greatly appreciated.
Kind regards,
Jake L
