Get good ranking depends on many factors. As you mentioned you have done with everything, so I assume you did the basic things, like - Keyword Research & Targeting, Optimize website as per the local search result (crucial, because Google search engine results change based on the location), solid website content & link building (though it is off-page).

Apart from that, there are many factors that are responsible for page ranking. Based on the common mistakes and our experience I'm giving you some suggestions.

• Check if you have duplicate content in your website,
• Mobile (Priority: HIGH) & Website optimization (I did check your site score only 6 in mobile & 39 in desktop on google page insight),
• Probably you get Crawl Error on Google,
• Might be there are too many redirections,
• Might be you don't have sufficient and consistent content on social media (off-page),
• Last but not least - you might miss GMB.

Please check the above-mentioned points once again and still if you would have the difficulties then come to me. I lead an excellent & highly efficient team, and we do white hat SEO best practices.
