I think as a first try I’d insert it here:

<?php
    bp_nouveau_member_header_buttons(
	array(
	    'container'         => 'ul',
	    'button_element'    => 'button',
	    'container_classes' => array( 'member-header-actions' ),
	)
    );
?><form>
<input type=”button” value=”Book now” onclick=”window.location.href=’#” />
</form>

<?php bp_nouveau_member_hook( 'before', 'header_meta' ); ?>

<?php if ( bp_nouveau_member_has_meta() ) : ?>
    <div class="item-meta">
