Cheap insurance provider for rental portfolio in Chicago

I have a portfolio of rental properties (>25) mainly in Cook County. I'm looking for a barebones insurance company (couple hundred dollars annually?) that can write up my policies to abide by my lender's conditions (125% of Replacement Costs or at least the Loan Amount, etc.).

Whenever there is damage I just repair it myself since 1) we have an in-house construction crew and 2) my deductibles are insane: believe it or not, I have to keep my deductibles around $10-15k/property to get my premium down to ~$1,000/property. I don't remember the last time I used my insurance for claims...they are really irrelevant to my case.

Anyone have recommendations?
