Simple handmake illustrations

URGENT PROJECT, needs to be done in 24H (by Wedneday at noon, London time) Our company is specialized in vehicle design and conversion. Our customers are mainly marketing agencies. Very often, we have to supply ideas and recommendations in very little time (24/48h not unusual). And as you know, one drawing is better than a thousand words. We are looking for one or two talented 'roughmen' who can supply simple drawings in a very short timeframe. Example drawings in attachment, to illustrate the style of drawing we are aiming at. Fixed budget: 50 USD per drawing. We have 2 drawings to start with (briefing will be added soon) => the budget for this project is 100 USD. No need to quote for less, no need to ask for more. Expected volume for successfull bidder: about 4-5 drawings per month. When quoting, please include at least TWO DRAWINGS you did in the past.
