Start by thoroughly examining the outside of the house or outbuilding -- not just the exterior walls but under the eaves, around windows and doors, and along the foundation. Look for split shingles and siding, popped nails, peeling or blistering paint, mildew, and rust stains. Once you've identified the areas that need attention, roll up your sleeves and make the repairs.
A true professional understands that it is his or her responsibility to provide a quality job for the homeowner. Professionals also know that attention to detail is a part of the job. While a homeowner might leave a bit of paint on the window pane, a dedicated interior painter for hire will make sure that these small details are handled properly, because a perfect job is the best calling card.
Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor. http://www.youtube.com/watch?v=b6_WEt9k_Hw&feature=kp
Prep. For new work the painter accepts the finish done by the drywall or plaster and once he accepts the work and starts painting he owns any wall repairs. Existing work is a different thing. I take a high intensity light and circle the kinds of defects with chalk so we are all in agreement before they start. Sometimes this results in a higher price and we have to compromise on how much to do... https://www.youtube.com/watch?feature=player_embedded&v=b6_WEt9k_Hw
With that said, here's the reality of that particular scenario. Painters do put water in the paint, but not for reasons you would think. Some materials need to have their viscosity manipulated in order to slow drying time, allowing gravity to 'smooth' out the product for a better finish. It also prevents 'drags' and 'sausages'. I personally try not to do it too often, but from time to time I have to. I want my client to have a proper finish.

Painting contractors must also carry out administrative and marketing duties. They prepare final accounts for customers based on the original estimates and any additional work. They analyze the cost of the job compared with the estimate to calculate their profit. They market their business through activities such as setting up websites, asking customers for references or contacting property maintenance companies with details of their services.
Painters usually find it hard to estimate the cost of prep work accurately. This is because the amount of work required varies greatly from job to job. The more the damage, the greater the amount of prep work required and hence, greater the cost. Dirty walls covered with grease have to be thoroughly cleaned for the new paint to adhere properly. Wood surfaces should be sanded 2 along the grain and dusted clean ($1.80 per square foot). Holes have to be patched up and caulked ($10 per square feet).
Painting interior walls is a task better accomplished with foam rollers, because they are easy to use and can evenly cover large surface areas quickly. Foam rollers and brushes should never be overloaded with paint, as it can create drips, uneven coverage and can take longer to dry. It’s easy to get frustrated when the paint is fresh and does not look like a photo from the paint catalog, but remember: that’s something that usually happens after the second coat dries.
To determine how much paint your house needs, measure the house's perimeter. Then multiply that figure by the height, excluding gable ends. Take the measurements with a steel tape measure, or reel out a ball of twine around the house and mark and measure the twine. If you will use a different paint on your home's trim, subtract 21 square feet for every door and 15 square feet for each typical window. Divide the final figure by the square-foot coverage specified on the can of paint to determine the number of gallons you will need for one coat.
