I'm not in the Sewage business, but I used to sell Myers who I believe supplies Menards with pumps and basins.
I would stay away from any Big Box store items for your project. Buy quality and it will cost you much less in the long run.
Zoeller is probably the best brand out there. Getting a complete package may have to come from a Plumber. There are a few Plumbers here who can help you out.
You will need a "Sewage" Pump, not a Sump Pump. Sump Pumps only move 3/8" solids, so the toilet part isn't gonna work.
