To be a consultant, first choose Only one module...
I know you have the experience of various module, but for consultant, One module is enough, after 3-4 years experience, then you can go for other module as consultant...
But always will be a integrated module...
Like as if you choose MM module, the integrated module will be WM/PP/SD/FI etc...
As you have worked with various module, Then I suggest Choose one module as per your interest and learn all type of configuration for this particular module...
You can get very good opportunity because you have the knowledge of various module..
But choose and apply as a consultant just for one module...
