Don't be discouraged. start again there's plenty of time. I too am sorry your post went unanswered.
I'm a good gardener but if I had a dollar for every plant that ever died on me..well I would have a lot of dollars....
Seed starting takes practice and we all learned from trial and lots of errors.
Sow your seeds as above. kepp moist, not wet, remove any cover and under light immediately when you see the first seedling emerge. (the rest can come up under lights) as PureHarvest advises.
Some well water can have too much soluble salts like sodium for example. To be safe with tiny seedlings, perhaps consider filtered water or distilled at the beginning. Or you can collect some rainwater if that is an option.
Best of luck and we would love to hear how it goes this time.
Never give up
