Maintenance and website development

I have several websites and I need assistance with coding, seo, server set up, security, and design work. ## Deliverables There are 6 websites that have different needs. Some of them are on a beginning stage and needs help with completing the goals for that website. Some need help with the SEO and marketing, and some need help to just perfect what is there. I have 3 servers so it is someone who can manage plesk and cpanel. I'm very interested in someone who can assist with security. My sites are always being targeted so i need to find someone who can keep the servers secure and the scripts are secure. ## Platform Some of the platforms consist but not limited to php, css, html, xml, and others.
