Good Morning, 

Thank you for contacting the U of M Extension Service. 

Please click on the following link all about purchasing lawn seed: https://extension.umn.edu/lawn-care/buying-turfgrass-seed-minnesota-lawns

All of the information on our website is researched based. So you can rely on the accuracy. If you scroll down, there is a list of retailers link. 

Here is another link about planting a fine fescue lawn: https://extension.umn.edu/lawns-and-landscapes/planting-and-maintaining-fine-fescue-lawn There are additional links at this website for bee lawns. 

We do not recommend specific landscape companies. I am sure you could have a discussion with some of them and decide on a contractor. 

Your information indicates you live in Ramsey County. You might contact the Ramsey County Soil and Water Conservation District : https://www.ramseycountymn.gov/residents/environment/soil-water-conservation

They have technicians who would do a site visit and advise you on the marshland/wet areas. You might consider a pollinator garden or a rain garden, depending on your site. 

Good Luck!
