Be careful with putting a $ amount on a puppy. It is really expensive for breeders to do all the health screening to get a healthy sound litter. You can get lucky with pups and have no health screening .... my shelter girl turns 12 next month and has been incredibly healthy her whole life, but I have known people who have had dogs go blind at 4 (testable eye issue in labs), or have hip dysplasia and the surgeries cost $''s to fix .... both things which could have most likely been prevented by good breeding.
You will need to figure out what kind of lab you want. The bench bred dogs are more laid back and have a bigger bone structure. The field bred range in size dramatically from very petite to very tall and can be very active which may or may not be what you want.
