Get a WordPress Theme Made!

[eyes]

Hello, greetings. I have a website with a PHP script that I haven't focused much on before. However, my competitors in the industry have switched to WordPress and used SEO plugins. As a result, I have dropped from the first page to nearly the second page in search engine queries. I do not want to buy ready-made foreign themes. I like this design that I have been using for years. I just need it to be adapted to WordPress and some improvements to be made in terms of speed. Is there anyone who can help me with this? If anyone is interested in offering a proposal, I will share my website privately. Regards.
