Mayyyyybe, just maybe, take into consideration that BP also has a proper dev team, a coherent design plan, years of work etc. While you are one person, with rather limited abilities and so far, due to the infamous first release of SS, demonstrated that you're not capable of working on truly massive projects such as those. Keep it small, keep custom assets out of the equation, make a couple small missions here and there, stay within FS2 territory before trying anything big and ambitious like a total conversion
(rich of me to say, my first release is a tc microcampaign but my point still stands).
Point is, it's not a good idea to work on what seems to be a massive project, by yourself, let alone on two whole acts of this project.
