I am a newb and hoping for some guidance on modelling some turbofan engines

I have this model of an A300, and I want to reproduce the engines in Rhino…As you can see the engine is 70 millimeters in length. I have a contour gauge that can help me create an accurate profile of the cowling, but I was just wondering if anyone out there has done something like this?..and could give me some pointers? I might even pay someone to get it done or even pay somone to tutor me…Thanks.

Also, the shape of the cowling isn’t perfectly circular…it bugles more on the bottom and it is a little bit more flat on the top. I can post some more photos if anyone is interested in discussing…Thanks.

One way would be to make the profile curves and then revolve them around a center point.that is if it is cylindrical
