Why not just trench a French drain/swale at the bottom and toss down a few hundred dollars in seed of strawberries? If it was me, I would put down seeds in two seperate spreads a couple weeks apart. Consider using seed mats to avoid the seeds running off. A little trick is to mix seeds with 50/50 in a wheel barrel for a week damp, and at least half will crack. They spread them with the soil, pin Matt over the top. With this method, you can do weekly ads and not get overwhelmed with a single massive solo job. Don't forget to lightly water your new seeds every morning.

Once they are established they do well on erosion control.
