Small macro or routine to write out a step file for a single solid?

I am new to solidworks and have not done anything with the API yet.

I would like to find out what I would need to do to create a small routine that would "with minimal number of clicks" select a solid and write out a step file to

the file:  c:\SW_solid.stp 

If anyone could point me in the right direction or point me to someone that is for hire to do these things I would greatly appreciate it!

Thank you!
