Probably can't help you with cost of breeding information, but here's my experience (in reverse). A few years back, I took a heifer to someone for breeding to their bull. Their requirements were:
Vacc. with IBR, BVD, PI3, BRSV, 5-way lepto within previous 12 months
Negative fecal or proof of deworming w/in 30 days of arrival and lice treatment w/in 30 days
Negative test for TB, brucellosis, leukosis and anaplasmosis w/in prior 60 days
Negative ELISA Johnes w/in prior 60 days
Sharing bulls can be risky. How concerned are you with what your bull might pick up and bring back to your herd? Agree in writing to the possible "what if's" (bull gets out or injured, things like that). Just something to think about.
