several colleges and universities offer courses in engineering... i know this to be factual as ive witnessed such offerings in various institutions of higher learning all over the country... as a result, there also seems to be an entire industry built around the knowledge and skill set thus developed, or focused by such expensively procured educational ventures, that exists just to assist those afflicted with the inability or unwillingness to try to do something for themselves. fabricators, inventors, designers, consultants, project managers, architects... these people put bread on their tables, feed their families, with the things they imagine and build in their minds... in the world in which i live, there is commonly an exchange for services rendered. a decent sort will usually compensate according to their upbringing in a way valued by both parties involved... ummmm... dude, daddymack has been offering his brain work for free and you havent even said “thanks, man”... id charge you an hourly rate because you tend to keep adding and changing what you want or i would place a pretty high price on it as a project to compensate the extra work that is inevitable. send me your plans and i’ll take a look at them for $425.00 us. we can discuss further compensation should i decide to take the project. thank you for your consideration and time.
