Customize or Create a Booking Calendar Contact Form for WordPress

OPTION 1: The closest plugin I can get for the functionality I need is this one: [login to view URL] You can create a new one from the scratch, or use the one above or any other contact form plugins as base. However, it needs to be customized. The most important thing is it has to support AliPay (there is a WooCoomerce plugin that supports AliPay and I can send it to you for your reference). The following functions have already been supported by the plugin I mentioned above, but they may need to be tweaked. Here are most important ones that I need: --Booking form optionally connected to PayPal and AliPay --If the user chooses AliPay (default), then the price is shown as the chosen currency. If the user chooses PayPal, then the price is shown as USD --Accepts different prices for different dates --Optional services field with support for multiple prices, multiple services or additional items --Discount codes management --After selecting the dates, the booking price is calculated and shown below the calendar. --Confirmation or Summary page after the email is sent. OPTION 2: Or you don't need to handle Payment methods at all. Just take care of the form section and feed the information to WooCommerce checkout page -- as WooCommerce already supports multiple method of payment -- you just need to tell it to form a checkout page with the information from the form OPTION 3: If you can write in node.js, I may consider use Ghost platform together with the form you created, and you can feed the order information to WooCoomerce checkout page. OPTION 4: You are an expert, maybe you have a better solution. Enlighten me!
