Not much for a recommendation in your area, but in rural SE MN along Pool 4 we have had about 1/2 acre done around our new build. The local guy we had do it has been great but I don’t think he goes beyond Red Wing – Rochester. He’s told me I’m in about $500 per “load” and I think I’ve got 3 loads on. We’ve swapped a lot of labor and let him hunt our land over the years so it’s probably not a fair representation of cost. We did have about a 10’ x 30’ area washout on a hill and he redid it for nothing blaming his own grade work for the issue.
On day 6 after seeding we clearly could see grass coming. Short waterings 3x a day have done it for us so far. The first ~36 hours he didn’t want any water on it as it set up. Once up 2” he said to slightly back off on watering to force the roots deeper to seek water.
I’d be curious to hear other reports on costs/results from IDO’ers
