There are not people at MSU who can help you directly, but I'll try to give you links to articles that you can learn from to do much of it your selves.  You could also inquire at a local garden center to see if they know of individuals offering this service.
Once the yard around your new house is final graded the first step you should take is to do a soil test. Knowing the type and fertility of your soil is the starting point to establishing & maintaining a strong turf that can resist diseases, weeds, moss and insects/grubs, look great and at an optimal cost. More info here: Don't Guess-Soil Test-MSU and MSU Home Soil Test-self mailer Tell them it's for a new build yard that will include clover.

Spring Lawn Seeding-OSU - I included this as fyi.  I believe the best time to seed a new lawn is about 20AUG with a mulch and begin irrigation until fall's cooler temperature and rains come.
Now lets turn our attention to the wild flower field...
You should identify the immature trees and consider how big they may become at maturity.  You'll want to consider removing the plants you noted above as they can be invasive and will overcome the wildflowers you wish to establish.

Establishing a wildflower field from seed is a multi-year process.  First the existing vegetation must be killed (including dormant seeds in the soil).  Then a seed mix is sown on the soil in the winter to cold stratify seeds so they will germinate next spring.  Growth height is controlled this first year to prevent weeds from going to seed.  Finally the second spring you'll begin to see fruit from your labors!

Native Plants for MI Landscapes-Shrubs - also consider elderberry, service berry and chokecherry shrubs as they attract native birds with their fruit .
You can also contact Prairie Moon Nursery (prairie moon.com) and Prairie Nursery (prairienursery.com) to get their catalogs as both sell a variety of native plant seed mixes. They also have good instructions on proper site preparation and seeding steps. Other more local seed/plant sources include Michigan Wildflower Farm (michiganwildflowerfarm.com), Wildtypes (wildtypeplants.com) and East Michigan Native Plants (eastmichnatives.com).
