Welcome Brian. For the best results you will need to table mount your router. The ideal method with moulding is to use feather boards to hold the wood snug against the fence and table. This ensures you will have a clean cut. This also keeps your fingers away from the bit and on your hands where they belong. Since you will be making a large quantity you should use a trick the pro's follow; start with a wide board and cut your profile on both sides, then trim them off with a table saw. This is much faster and easier to control than running small strips.
