Now, for RPG purposes, it may be worthwhile to expand slightly: WP expenditures and earning are abstract. When you take on additional objectives, you don't find a crate with cash waiting for you back at base.* Sometimes the WP represents favors or 'good luck' coming your way, while spending WP can be seen as you cashing in on your contacts, your preceding career of resources, favors and even luck. Right place and the right time.
So, that could mean that as far as the story to the players is concerned, you're getting a "free" JumpShip ride, which might actually be you cashing in a favor, or now owing someone. Perhaps you blackmailed the JumpShip's owner, (who'll exact revenge later) or perhaps someone else forced the JumpShip owner to take you on, someone who'll come knocking at a later date, or maybe it's someone who's trying to lure you in to a trap by making sure you get to your mission that's 'destined' to fail...
Bottom line: WP are supposed to make your life easier, but never let them restrict your creativity or your story.
Added suggestion: see what happens when you present Tracks and objectives without telling the players how much they score for each objective... It takes all the pointscoring out of the equation, and puts a lot more decision-making in the hands of the players.
Just make sure to never tell them what they scored, keep giving them more decisions.
And make sure that you're good at expressing which objectives are more important or have a higher priority.
