If you are managing the project yourself you need more than software to get things done on time these days.

Systems need to be put in place and I would advise a good accounting department along with a strong software system. 

Here in the Bay Area it's called the "tech wizard special" -- computer science degree, 7 months on the job as a six figure software engineer, 3.5% down (they pay very little rent, sharing a 2 br apt with 5 other young/single techies, allowing for very rapid savings), and boom here's your $700k mortgage. 

I just need to learn a software to create them.

So I've been researching different REI software and would like your opinion on which ones you prefer over the others.
