Job ID: 30725600

Budget: $5,000 – $10,000 AUD

Hi my name is Greg .
I am looking for someone that can develop a plugin to sketch up for our SIP panel housing system to automate the process as well as giving us costing and purchase orders.
We have developed our libraries of all materials but now we are ready to go to the next step.
We are looking for someone that understands house building and is very efficient in programming and automation.
We need someone to understand algorithms as well so we can have automation .
We need it be made simple so most people with little skills can operate the program.
We need this done asap , but with a complete stage process of what can be delivered and what we expect in outcomes.
And as each outcome is achieved as agreed payment will be made for each stage .
We have tried this a few times without much success with people not delivering the agreed outcome .
We are looking for a skilled person that has the right skills to develop our program.
