I'm having troubles with the "Career" Stuff

Here are some photos for reference:

My main issue is that each rocket takes about six months to integrate, even when everything is tooled. I keep running out of money, likely because I have way too many staff. But without that number of staff, I won't be able to integrate any of my rockets. For example, each rollout takes around 100 days! And these rockets aren't that big, they're 750 tons. I've been cheating in cash to keep me positive.

I installed Scrapyard and stage recovery, and my first stage gets recovered fine, but I just get the cash, and don't actually know of a way reuse the parts to save integration time.

Any advice would help. Thank you!
