Reservation booking system for DJ service

I hope this is the right place to put this. I am looking to change my DJ site to word press but I need to find a plugin that will do what I need. Right now I am using DJ Intelligence it integrates with my site I do not have to have some that works the same but close would be great.

The system allows customers to check to see if I am open for a date then allows the to get a price quote by picking what type of event ie… wedding or just a party. They then pick what services they want such as karaoke, dance lights, wedding service music and the amount of hours the event will last and so on.

Things such as lights and karaoke are charged as a flat fee and the time is charged so much an hour. after that they get the quote it gives them the option to book their event then gives them the option to pay a deposit which is 25% of their total or they can pay it all, if they only pay a part of it they can come back later and pay the rest to my Paypal.

I am willing to buy the plug in as I know most of the one with all the good options have to be paid for. I am thankful for any help and any pointing in the right direction. If it would help here is a link to the date checker which is where the customer would start on my site so you can go though the booking form to see how it works. Date Checker
