Any marketing specialists/business men out there?

[meleader2]

i recently got a piece of software i wrote copyrighted and am actually very very nervous. it is something that (at least it seems) the audience i am focusing on needs. i was told i could get away with selling it for $500 a pop, but am settling to do it for $300 to attract smaller companies.

my question is (and i'm sure it probably won't be answered) what is the likelyhood of being run over by some competition like Microsoft if and when they get wind of this area of software development being an untapped resource.

i'm a complete newb to marketing as well, i'm a comp sci student super senior status and i feel like this is my way out to become independently wealthy yet if i MESS THIS UP it will fail.

i need all and any thoughts for marketing and protecting myself.


thanks in advance.
