LOL I work for myself mastone (ok Survey)...and its a pain in the ring sometimes...but yes you do have certain freedoms you dant have under a company...however...you do get all the headaches...getting subbies to do quality work (cant do it all yourself)...on time...etc etc etc...so that would be the first thing to think about. Staff (help you will need)...equipment...etc these are outlays that you will have to wear the cost of...if thats what you mean by making the saga.
As for supervisors in a company you work for..well its exactly the same but this time around you will be dealing directly to a client of some sort to sell your work...trust me...it aint easy. I deal with designers and architects all the time mate...and I have some specially made duct tape to tie me down when I want to break somebodies ribs (yes it gets that bad). Now I know construction is a different fish but the general arrangements, timelines, designers and clients are the same.
If you could start out with some shorts and try to get it onto a youth TV or something similar..why not..good luck with it mate...it will be a long road as Im sure you know.
