543402 Need work on URL: htaccess expert

I recently migrated my Joomla site to Wordpress. In Google many URLs from Joomla site already get listed and from where we get most of our traffic. I need someone to help me 301 redirecting my old Joomla URLs to new Wordpress URLs for SEO. Joomla's Article URLs consist of article ID in it. I am looking for a expert who is experienced writing .htaccess rules and some other way to achieve the same results.
