Shopify Promotion Expert

Thanks for reviewing my post - please do not reply if you are not an expert in this field.

I have a general shopify store with over 200 products for sale. It’s been over 3 weeks now and I haven’t made any sales. So what I’m I looking for?
1. You will know what techniques to use to improve sale.
2. You must know the Ins and Outs of how to manage the store.
3. You must know how to use Facebook Ads and Instagram Ads.
4. You will find influencers that we can use to promote our products.
5.Expert knowledge of SEO

Basically your work will be to improve the sales on my shop and you must have proven evidence of doing such before.

When you reply. Let me know your previous work experience and what strategies you will implement to improve sales on my shop.
