Hello! I need more help fore create a 3 in 1 machine!

Hello everyone!
I need a lot of help! I am new, beginners!!! and do not know where to start!

I saw a video on this site where with small steps, the car was changing function!
I want to create a machine that cuts and records with the laser, which uses CNC, and 3D printing!

I wish someone would tell me step by step what to do and what to buy to achieve it and give me the instructions! or I am willing to PAY someone to bring upon me! Thank you!
