I always have a problem with forms being emailed for things like reservations, bookings, purchasing items, etc.
What if a person submits the form and then realizes they made a mistake two days later?
They fill it out again. Did the recipient see the 'correct' email? What if the recipient was on vacation? What if the second email ended up in a filtered folder?
Doing business that way is really a bad idea.
Your customers register for free and create a profile or account. Both the customer AND the business person see the same information at the same time. Any changes, corrections, cancellations, partial billing, etc. is handled by the scripting/database programs.
Email only used for brief confirmations or messages to let both parties know that the account needs to be looked at.
