If it is a commercial project, then people who help are normally called consultants. They want money.
If it is a shool project, then people who help are called teachers, and get a salary. Geting someone else to do the school assignments is called cheating, and means that incompetent "developers" will get released into the job market without the required knowledge.
If it is a hobby project, then the definition of "hobby" should indirectly mean that most of the enjoyment is to find a solution. A working final product is just icing on the cake.
