Create a B2B Ethereum blockchain like ledger for inventory management and product registration

I'd like to create our own proprietary blockchain inventory for live marine fish and corals we ship and receive. I want someone who can work about 5-10 hours each day on the project 5 days minimum per week. You will be working on a shared screen either through teamviewer or joinme. I monitor all progress and all files worked on will be edited locally, and at end of day we commit to our github. This is a project for someone who prefers working on longterm client relationship.
