What do i need ,will this work for me. If someone could please answer this for me . Very small place to mount board .6 motors variable speed is needed also. Thank you

You need more than the motors and the bluetooth module but you have not told us what else you have.

What are "micro rc geared motors"? Post a link to their datasheet or at least provide a photo.

What will be sending data to the bluetooth module? What will be the format of that data? Or can you design the format yourself? Have a look at the 3rd example in Serial Input Basics
