I was wondering if anyone could recommend a price for selling these items (and perhaps the Engineering IV items as well)? I would like to start selling some but I have no idea what a fair asking price would be (which would also cover the cost of my own harvestors, maintenance costs and crafting time spent). Thank you in advance for your assistance!

Check the bazaar. Although many of the prices there are too low or too high, they will give you a general idea of what people are trying to sell for. Of course, just because someone has a harvester for 3K on the bazaar doesn't mean they'll actually sell it for that price.

You might also do a Search in CTRL+P for other Architects and simply ask them how much they charge. You'll get a lot of high and low prices, but you'll probably be able to figure out the average quickly.
