Need help with creating a 3D work flow simulation

Hello,
I am working on creating a 2-3 minutes video clip in which there will be a combination of some 3D work flow simulation and real video shooting.
I am looking for someone who can help me with 3D simulation part.
I’ve collected a few video clips online from other expert what I need is to use these concept, create and combine them together for my own purpose.
I am amazed about Blender’s effect, but I am new to this, so need your help.

If interested, please PM me with your quote/time and I will provide you more details

Thanks very much

Here are the samples I gathered:
Create a sink - starting from 12:54; final effect from 24:20


Water flow in a pipe

Adding particles in fluid

Similar effect I would like to show
