In need of a inventory management system.

Hi!
I am looking for someone who can create me a management system to keep up with inventory, sales and shipping all in one place.
Ideally something "alike" *Zoho inventory management system* but with functions like SKU and barcode generator (Also ability to use with a barcode scanner), implementation of platform such as Ebay and amazon. A possibility to create within shipping labels with chosen websites (mostly using Boxtal.fr and Fedex).
To be straightforward, I don't have a big budget but I am open to discuss it. Only looking for someone serious who is dedicated and honoring his engagement.
Thank you very much!
