Need Help Completing my WordPress Website

I have a health coaching business that needs a website. A friend helped me get the site started on WordPress (https://brennabray.wordpress.com/) but was not able to bring it through to the finish line, so I'm looking for some additional help.

I have a variety of additional resources on/for the website, that can be accessed upon request in a googledoc (https://drive.google.com/drive/folders/14DKTMBGYCXrRPtgeGprxQh5ILjdH25Oc?usp=sharing).

The "FINA Website Design" pdf (attached) shows the design I'd like to use for the homepage. I have this design in a variety of different formats (pdf, psd, tiff, jpeg, exr, heic, jp2, png).

I also have similar design files for the ancillary website pages (these are mostly already plugged in but can be found in the folder "Website Design Drafts" in the google drive folder)

The powerpoint doc "Brenna Bray website.pptx" and the word doc "IIN website_instructions.doc" (attached) provide some higher-level detail on how I envision the website.

I have photos that can be plugged in to various parts of the website (mostly they already are but these are also in the folder "Website Photos" on the google drive)

I have word docs with all the content to be plugged into the website (in the folder "Website Text Content" on the GoogleDrive)

I also own the domain www.BrennaBray.com. If possible, I'd like for the WordPress site to link to this domain.
