The cost of custom enclosure design services depends on the scope of services requested and engineering requirements of the enclosure, so its best to get a quote for your specific project. In general, a product in the consumer electronics industry requires an additional service of industrial design to create a sleek looking enclosure, this adds cost when compared to a product that is not customer-facing and does not require industrial design service. Similarly, for engineering requirements, an enclosure that requires IP68 water resistance will cost more than a simple housing that does not need any type of water-resistance.
