Thinking of getting dental implants. need info?

I feel as a child and broke my teeth. I need to have them recrowned and also I need to have partials put in 3 spots where I have lost other teeth on the top row. I have alot of dental problems and was thinking of having the top ones removed and getting dentures. What are the steps and cost if anyone knows. I have excellent insurance but would still like a price to get a idea before I go talk to a dentist. Thanks
