You control the acquisition of wealth. There is no expected amount of treasure or magical items in 5e. Therefore you can make gold, and by extension resurrection, as limited or not as you wish. 1,000gp under these circumstances can be either pocket change or a major lost resource. Personally, I will be going with the latter and I think that is enough of a negative consequence, especially if it means the party now has no further funds for a resurrection.
Also, the 1,000 gp is only the cost of the material components. A high priest would certainly want a lot more for his spell casting services. In my Ptolus Pathfinder campaign 30,000 is the normal total cost. Pg. 159 of the PH discusses spell casting services but gives no formula (it hints at a quest or service). I believe in 3E or Pathfinder it was CL x Spell level X 10gp + material component costs. I would suggest at least this.
Here are some additional ideas I have to limit the impact of resurrection/raise dead in the campaign world:
* You can only be resurrected if you have not fulfilled your destiny (I believe this was a 4E concept).
* Elite assassins have the power to deal permanent death. If an elite assassin kills you, you can't return from death.
* Common folk are generally frightened of resurrection as it can go very very wrong. Think Khal Drogo.
