Create a Software/Operating System for our Company

In short, we are a distributor in the manufacturing industry. We buy product, either sell it as is, lesser quantities, or add value to it (fabrication). We have been operating off of Microsoft excel and google sheets for a very long time. It has worked for the most part, but now we are growing at a rapid pace and looking to simply our office processes to make us more efficient, give us better transparency and traceability.

Looking for a software developer that can create the following for our company:

Quoting System
Inventory System
Shipping/Receiving System
Customer Data Base
Open Order Report System (what's on order and status)

Much of this has already been created in google sheets with some macros involved. I have been trying to build the skeleton of what I am looking for but am at a point where I need some help. Really, we could work through google sheets if you are proficient with macros however I am looking for a long term solution to help our company grow with efficiency. There are softwares out there that we can use but they are either crazy expensive or do not cover all aspects of our business. If you can help me, I can refer you to many other manufacturers in the same boat.
