<div class="center"><p>An on-site photo shoot, extensive photo editing and delivery of appropriately licensed images included in all proposals.</p></div>
Or –
<p class="center">An on-site photo shoot, extensive photo editing and delivery of appropriately licensed images included in all proposals.</p>
