Latest Centos7 in working virtualbox guest (with guest extensions); Win7 is the host

Hello- I need the latest version of 64b Centos7 (Currently build 1804), running in the latest version of VirtualBox (Currently 5.2.12, build 122591) for 64b Windows 7, **with guest extensions** compiled and running on the CentOS7 guest. I also need a brief text document describing what packages were downloaded with yum, what symbolic links were created to build the guest extensions, what build of the guest extensions disk iso was used (if not the one supplied with the latest VirtualBox build), etc. Building the guest extensions on CentOS typically requires hours of googling what packages to download, googling for workarounds to build errors, etc. I don't have time right now to do all of it. Centos7 should be installed with one 'guest' login. You should check to make sure guest extensions are working (cut/paste, window resizing, shared folders) Project will be deemed complete when I can recreate what was done to get the guest additions built (I'm very good at creating Ubuntu and Centos virtualbox images, but never had any luck getting the guest extensions built and working in a short time). Thanks
