Working with a partner that produces custom concept art for you will enable your business to freely pursue other tasks, saving both time and money. A good art service provider will always jump into projects quickly and keep only the most capable artists on the payroll, allowing projects to progress with minimal delays and bottlenecks. Given the strong guarantees provided and documented by most partners, this is also a safer business model for hiring than recruiting freelancers, for example. Some partners even provide specialists that directly join and work with your team, augmenting it.
