Building the two factories is one action. Therefore I would assume that you sell shares in order to be able to afford the action as a whole. Nowhere does it say that you have to split it up into sub-actions.
Placing the administrative marker (and paying for it) is also part of the same action, by the same reasoning I would assume you total the cost of your action, otherwise the rules would have mentioned that you need to fund the sub-steps separately.
correct. It is all one action and you summarize the total costs before selling shares in emergency.
Take a look at Spinning Jenny Rulebook, page 11 bottom right: all costs are paid together, only in the first games you should pay administration costs and single costs step by step to keep track of what is going on.
Note: the additional action is separated! You have to complete your main action before taking a development marker. Thus, you may have to do an emergency share sale for machine action and then another one for paying the inventor for the first time (second etc. payment is part of the main action!).
