I believe the EHAS website does not allow home kits. Passport Health has been mentioned here, I used Clear Wellness out of Chicago for a recent trip to get my Covid test, it is a pain clinic that also is allowing non-symptom covid testing. Medicare was free, it was $175 for me as I was out of network. We had our test on a Tuesday and had results Friday afternoon. Clear Wellness right on Michigan Avenue, but I see that Passport Health has an office in Milwaukee, no idea what they charge. I have some questions into Jango Bio, who are doing free testing right now at their office in Fitchburg (2997 Yarmouth Greenway) to see if their test qualifies for the Rt PCR testing requirements.

Not sure where in Wisconsin you are from, but hopefully some options for you to explore more.
