Debug and speed up Wordpress Website

Hi, Good day, Our engineers were conducting a routine check and have identified that your website is infected with scripts that is trying to overload the server. Please see below for the infected file location: =============== /home//public_html//wp-content/themes/sket/[login to view URL] =============== To prevent further hacking/spamming, we have placed a POST block on the account to prevent all POST functions made to the account. To access and make the changes to the website, you will need to edit the .htaccess in /home//public_html// to add your own public IP as follows: <Limit POST> order deny,allow deny from all allow from [login to view URL] allow from [add your own public ip] </Limit> To know what your own public IP is, you can go to [login to view URL] For E-commerce website, it is important to be malware free so that the POSTBLOCK can be removed. POSTBLOCK set up will restrict more malwares injection and prevent malware from taking over your email service to send out spam emails. However, POSTBLOCK also restrict functions like customer/admin login, customer purchase action, and contact form as well ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is the error message I got from my web host and also the website and the admin panel is extremely slow in loading. I will require someone to access my admin panel and edit the files needed to prevent my errors and also to optimize the script to speed up the loading of the website. Simple project with a low budget. Please proceed if you can do it below SGD 30. Any price above that I will reject your bid. Please message me for the URL. Thank you
