Need help with model rockets?

Question

I am going to make a model rocket with 3 engines, otherwords, 3 stages.

I need someone who works around model rocket engines to help me.

I want 3 types of engines that can fit together well, as in the 1st rocket that goes off, can fit together and make the second one off and so forth. I believe that these rockets are called B or A somethings?

If possible, under 500 mteres. Thanks in advance
