also since you are 720 and 480 miles away, your $8k is not equal to their $8k (remember recruiting is not just about money, it is about effort.
at 720 miles you are probably spending close to $800 for a HV and over $1,300 for a CV. since SIM is recruiting at around 200 miles, they are spend around $400 for a HV and about $1k for a CV.
so with that in mind, you would need to spend probably about $15k just to get even with them (if they do have the $10k into them)
