If you have never held a can of spray paint in your hand, and have absolutely no idea of what it takes to paint something, AND you are restoring this to "show quality", then continue with your approach.
If you can hold a spray can in your hand and understand have even just a fundamental understanding of painting, and actually use your truck as a means of transportation, you should do this yourself. You will save lots of money, and anybody knows that putting a top-notch paint job on a series, is like polishing a turd.
Sand the existing paint until it is smooth; don't worry about "stripping it". feather the high and low spots, prime, then paint it.
The only tricky part is matching the exact color of pastel green. The Limestone can be substituted with a can of Krylon (I believe I have heard people on this forum call it "almond"). And since the Limestone is not located adjacent to another location that has the Limestone color on it, matching is not an issue. However, the Pastel Green is adjacent to the rest of the vehicle, so it is critical that the colors match. You can use the original paint code, but odds are, if the moon and the stars aren't aligned just right, the color won't match. This is why I would take it to the closest autobody paint shop (Sherwyn Williams, Dupont, etc.), and have the color matched, and see if they will fill it in a couple of rattle cans for you. This is very expensive, but eliminates the need for tools and know-how. When I say expensive, I mean about $30/can, but still way cheaper than the alternatives. Hope this isn't just a bunch of rambling.
Good luck.
