Estimating effort to implement for a 30 person company

Hi guys

I’m looking into ERPNext right now.
We are a 30 ppl company - I guess ist a mixture of manufacturing and service in erpnext terms :slight_smile:we buy and assemble hardware components and deploy our own software with the A’s well as supporting the installation on site.
Am I assuming write that I will need the manufacturing and service module ?

Is there anyway tonestimate a project budget ? I don’t care about 10.000 more or less. I’d just having a hard time finding any hint how much such a project would be.

Thanks in advance
