Hi.
Installing akeneo isn't complicated just we need ssh access and root account.
Akeneo installation need a VPS not shared hosting because we need to use some commands like composer and apt (if we afe using ubuntu or debian)
About the addons is a little more complex because we need to modify some lines of code from akeneo.
I was reading about your plugins requirements:
- Table attribute: paid addons, installation complexity medium-high
- Pimgento (Magento 1): free, but be advice about dev reccomendation: "his version of PIMGento2 connector will not be maintained anymore by the end of 2018. We kindly invite you to visit the new PIMGento2 (API) connector page ([login to view URL]). "
- Custom entity: free, installation complexity medium-high
- Custom entity enrichment: I cannot find it, maybee is the last one?
I've installed akeneo without problem and I've realized akeneo migrations previously.
Open to questions,
