That's up to you. Different drivers and crew chiefs will be looking for different things when considering a race team to join. A contract that one may accept may not be accepted by another. Remember, if you're starting out at the lowest level, a driver or crew chief from a higher level most likely will not accept your contract offer no matter how high. Also keep in mind that you have a budget. If you offer contracts that are too lucrative with high payouts for poor performance, you may eventually find your team in financial difficulties. You should note that if you break a contract, your team's reputation will suffer and there may also be financial repercussions.
