Hello. To install certificate on each sub-domain, you have to add the SSL settings to each Vhost. If you already have a script that creates sub-domains, I can modify it and add possibility to append required SSL options to each Vhost. I can start right now, and complete the project fast, with a highest quality and without any impact. Before i start i need to check your scrip's body. And i only need SSH access on your server to complete this project. You may pay only after job is done and you are satisfied with the result. Promise to do my best. Thanks in advance, Stan.
