I have not but I've been meaning to. There are DIY kits from Amazon you can order or you can get one done thru UMass

Tenacity(mesotrione) has a proven track record for pre and post-emergent crabgrass control. It works on other broadleafs weeds as well. Low toxicty. It's sprayed on.
There's Barricade(prodiamine) that comes in products like The Andersens and there's Dimension as Scott alluded to that sold under Lesco or Jonathan Green.

Spring Seeding is not ideal in our climate as your competing with weeds at the same time. It's best to wait till now to start the process.
The Andersens has a new product that may buck that idea.

Grabbed 25# of the Black Beauty Ultra, a bag of Mag-I-cal plus, and a bag of Love Your Soil. All Jonathan Green Products. No starter fertilizer in stock, so I’ll probably get that online.
This is what is looks like right now. It's overgrown a bit since I haven't cut it in a couple weeks. You can see the Dig Safe marks on lawn for Fence install. Fence will be going from just to the right of there up against the house straight out 90d to the tree line between my neighbors house. It's give us a screen from the street to the pool in back yard and will create a small lawn behind it where I will be putting my Davis. Not an ideal spot but I don't have anywhere else on my property to put it. I am thinking of putting my anemometer up on the gable end of the new garage with a wireless transmitter to the station.
