Contractors, unless you have a working relationship with them, normally do not want you bouncing ideas off them.Understand what their hourly rate is, have a discussion with them that you are okay with paying them an hourly rate if they walk the property with you and provide you a scope of work along with an explanation of what you can/can't get away with in regards to improvements.ask them if you go with them, if they can credit you the amount that you paid.Once you develop a working relationship with a few contractors, you can bounce ideas off them and expect quality responses.I do not invest in New York.Best of luck.
