Build wordpress website from scratch + Plugins modifications

I accept new freelancers but at a lower price. I also spend allot of times with my freelancers to work to the best of my knowledge. **** YOU NEED TO KNOW HOW TO MODIFY WORDPRESS PLUGINS *** Payments will be made when the job is finished ( No milestones, no upfront,hourly basis, nothing) until the job is finished and stable. You need to know how to setup and optimize lunux cloud server ( I use digital ocean ). It is already mostly setup but it is not optimized and it has no firewall. Https need to appear also right now its partially done. This is for the whole job from creating the website design to doing the set up of the plugins/modifications and set up the server etc. I need some one to create a clean, well coded/ fast and seo optimized and responsive on any devices and browsers wordpress website. I will provide you with a clear guideline for the design ( I got some sketch I made ) I will provide you with the plugins that I will use for most of the features of my website. ( About 9 plugins which include some addon to the original plugins ) You need to be able to customize the plugin and also set it to work and be functionnal with my content/website and this need to be included in the fixed price. One of the plugins need heavy modifications ( more than the others ) so you need to know what you are doing Also it need to be secure and stable which is also included in the well coded I guess. You also need to setup my cloud server and the website into it. I will test the website with google speed test and other testing sites and it need to fix what they suggest. You cannot resell or give my website to anyone this will be rightfully mine after I pay you for the job.
