Modify a Sharepoint modern website

I would like someone to talk with me about some changes to a modern Sharepoint Online site, do some research, then come back and coach me through the changes. I can't provide access to the site, but we can share screens, discuss etc. The changes I would like are a rotating carousel of images, a web-part which displays text from an item selected randomly from a list, and finally a web part which privides clickable links from objects on an org structure diagram. all can be discussed and revised if necessary.
