We have experience setting up an online shop for drop-shipping purposes, although where you get the inventory doesn't really matter with online commerce hosts like Shopify, BigCommerce, etc.
We would recommend 3Dcart if you have below 100 items , they do not charge per transaction, only a monthly fee and their templates are very up to date.
Once set up and a quick tutorial is given, you can then update and upload on your own with no problem.
Needed before project approval:
"Domain and Host"
If you wish to go to 3dcart, check out their prices. If they are reasonable, you can even purchase a domain with them.
