Seeking advice and an honest review 🥺 of new Jewelry Brand on Shopify

Hi!
I am helping my sister build an e-com site for her personal woman's empowerment brand and i'm supposed to be helping with the marketing setup. I've never worked in e-comm before but i've been watching a bunch of tutorials to get started.

To give some reference because I think it'll be vital to selling it even on the website: She is about to become a certified psychologist is really passionate about female empowered and childhood trauma, shes wanted to start this project for a few years but since the fires have ravaged los angeles where she lives, shes been forced to make it or break it now as a last resort.

The brand is going to be focused around her but shes camera shy and im working to get her creating content, so for now we are trying to launch and at least get some sales in to start making some $.

Can i ask you to honestly review our site and let me know what you think about the design and what can be improved for conversion optimization when we start ads? Also, regarding ads: we have almost no budget, but im saving up for when the launch time eventually comes...

  1. How do i determine a budget for the products? For example: most of our items cost less than $100. What should we be spending per day?
  2. In regards to campaign structure, what type of ads should I start with? And what structure should we use?
  3. She intends to start doing counseling soon and so on and tie that into the brand, but until then how can we showcase the big brand idea more on the website?
  4. Right now we've setup the site so its ready for orders hence we just need to start with the marketing... Ive seen peopel talk about google merchant and google shopping, how does one set this up and is it worth it?
  5. What marketing channels should we develop? I was going to just create posts for facebook, instragram and tik tok, but now i realize that email and this google shopping may be good alternatives...

Thats all for now, i have so many questions but these are all that i have in mind to start with... Its just two of us and time is of the essence so feel free to leave any other recommendations you have regarding what we should consider.
