Different description for each option and different amount for different option

If you use the combined option in the reference field you can have the options as you want.

Look at the form called ‘Form with selections’ on this page: https://quick-plugins.com/quick-paypal-payments/paypal-examples/

I want pre-set option, all is need to select a package by user/customer end.

I’m really confused by your request. The combined pre-set option does exactly as you want. Do you look at the example form? It has the code format you need.

However, I figured out some option and I’m okay with that. Great thanks for this plugin.

Excellent. Thanks for the compliments
