Websites are like gardens: you build them, but then you need a gardener to maintain them because you want them to always look good. You can build the garden as a one-off project and spend a whole lot of money in one shot. Or you can spend smaller amounts of money on a monthly basis and have your gardener work on it and adjust it as new ideas pop up in your mind. As website builders with more than 1450 projects delivered, we can do both: build your website as a one-off project, or we can work with you over a longer period to deliver a great-looking website. To answer your question, yes, we do work with finite contracts that start at $5,000 per project, in which case the hourly price we are using to estimate the project size is $1600/hour compared to $110 to $120/hour for retainer work. However, customers who chose to build their one-off projects on a retainer instead of a finite contract: Enjoyed discounts of up to 45%(!) due to better hourly prices. Received top-notch  monthly personalized suggestions from the Outsourced CTO (your chief gardener ) on how to improve and keep the websites in good shape. Lastly, they had websites that looked great both when they were shipped as well as months and years after that.
