My tired but so far true method is smple:
Fully load your store with product, pick a resonable price then jump up + down by 10% and put the formula
(Price-cost*) x Amount / time ** space***
* Cost you can buy for, or sell if you make it
** Hours usualy or to be more presice use minutes
*** I get the stats for 1k of space usualy to compare but its up to you if you want per person ect ect
If you do this for 3 prices you can tell what way the numbers are trending then increase/decrease your price and do it again, for a new market it takes a few goes but once you get the hang of where prices are sitting you can do it in seconds. Its easy done in excel, just ask me to send you mine
Now that you have this you can play with the numbers to see profit per hour, day or even second
You can also see the profit each type of building brings in. ie: Gas Stations to Factories to Mines so you know what area to focus on
Also ill happily have a play at your co if you want

I assume you trust me enough

, seriously I do want to have a look so if you want ill show you mine if you show me yours
