Hi Karl,
If you do not mind, could you please share link of existing website with me over chat so I can review it and share my personal views to refurbish the same. Also, please let me know in which framework(Laravel, CodeIgniter, CorePHP, CakePHP, WordPress) is your website developed so that based on it I can provide you my dedicated resource who will only work on your project.
Waiting for your valuable reply.
Regards,
Manish Narola
