Answer 1

if (mail('services#brickboys.com.au', 'Service Enquiry', $body, 'From:' . $email)) {
echo (mail('services#brickboys.com.au', 'Service Enquiry', $body, 'From:' . $email))."Thanks for contacting us.";
}
The problem in these lines you're calling mail() function within the if statement. You just need to echo your message there doesn't need to call the mail function again.
This is how you'll write your if statement.
if (mail('services#brickboys.com.au', 'Service Enquiry', $body, 'From:' . $email)) {
echo "Thanks for contacting us.";
}
