Custom Wordpress with Facebook "Events" Integration

I need to have a custom wordpress template created based off my Photoshop design files. The site will require integration of "facebook events" In calendar page as well as a small shopping cart using paypal as a payment processor. The following are the specifications given to me by my client. If you can meet all his requirements please contact me. Thank you. I currently have it on a wordpress and just recently downloaded pagelines themes ( a drag & drop system that supposed to be easier) but got complicated so reverted back to the current theme. My goal is to have an easier site to navigate through for someone wanting to reach the site for event info. The info is there but it isn't the most attractive thing to look at. I would however like to have the following tabs in no specific order. "Get to Know the Food Trucks" I would like a page I can add to each month. An about section for each truck. I would like a page that has tiles or cards you can click on and read a bio about the truck, watch a video and also get the trucks contact info for catering and such. "Get to Know our Sponsors" A page where those who sponsor certain events can also have their details and bio. Calendar I currently have a calendar which is a plugin. It is connected to my Facebook page and any and all events I post on the page automatically import to the page and show up in chronological order. Every time I update the event page on Facebook; change the list, change the date or add details to the event it auto updates. Note: on Facebook event pages expire 24 hours after the end of the event so if I don't get in there and change the date to the next one I loose all the invitees and comments/photos from all the previous events. It requires maintenance but it also avoids creating a new event page each time and have to invite everyone again. It can get old and we'll lose attendees. Additionally, a great feature is that any message I type on that event page gets a notification sent to everyone that is "going". Unless you know of a better way to integrate I would really like to have the FB page be the source for the calendar. Now, you will notice that on my page I have an event page I created and it is different from the calendar page. It would be great great great to have the event page also update off the calendar page or if they were both the same (if the event tab could take you to the calendar page for that event. I don't know maybe you do. Events Same info as above Store T-shirts, stickers for sale. Finally, I have trucks, sponsors and others who want to advertise on the page. I would like the event pages, the home page, the info pages to have Ad space. The Ads will be created in-house so no automatic google ads. I prefer to have those advertising on my page be related to the page.
