Hi!
My name is Eric and I'm really interested in your project. So, as I understand, you need a booking system for bowling parties, it has to be using Wordpress, and it has to have some concrete functions (Able to block dates, periodically if necessary, and has to have the feature to send automatically a mail to the website owner). Well, I can assure you I can do that!
I have years of experience in Wordpress, and I've worked on hotel booking webpages, so even though this project has some specific requirements, I'm ready to start and make it just as you asked. Even with the multiple text based fields and, of course, with the datepicker!
Please, if you have any kind of doubt don't hesitate to contact me through the chat, no strings attached!
Kind Regards,
Eric.
