I share the view expressed by Jan and Agaricus. If you want to be taken seriously in a professional industry, present yourself the way you'd like to be considered.
Remember, when you ask someone to provide their service to you for "the cheapest", you are suggesting to them that you are not willing to pay them fairly for their time. Many people earn their living keeping planes in the air. Those among them, from whom you really want to learn, won't give their time away as "the cheapest". The high regulation imposed upon aviation by our respective governments, results in a lot of people having to do a lot of work to keep the plane ready to go. If you would like to fly, their's is the cost.
You might as well get used to it now, flying costs more than most other activities. Your training will be less pleasant if you, and the people around you, feel that you're after the cheapest all the time.
