Hello I can provide you the solution. But the description of the project is confusing. You listed three softwares. Clear me, if you want load flow analysis using any one of three softwares? Or using any two of three softwares? My rate is fixed, I would charge $30 for one method on one software. So as many you want, you can multiply with $30.
Let me know if it is acceptable to you, then let's start this right away.
Regards.
