You can get all of these by modifying the files in your users/(name)/appdata/local/CSDsteambuild folder. I changed the bckndata1file file. Just open it in notepad. Look for the lines gchoreswaitvar and gcustomerwaitvar and make the numbers higher. Set them at around 2500 and you'll have like 5-6 minutes each, plenty of time. I dont know why, but this doesnt work in the iron chef and other special challenges but they're probably buried in there somewhere as well.
Cash is the Gmoneyvaluevar line at the end, make it as high as you like.
Just remember to back up your original files, or at least make a note about the things you changed.
