The trick to doing smd soldering is reflow. On all budget all you need is a hot air gun, if you put solder and flux on the pads manually before placing the components. With a stencil and solder paste you can save the time tinning the pads, and placing a component every few seconds is quite possible. So if you work really hard and quite possibly break your back you can assemble this board in a day :)

If you're working with stencil and paste, my understanding is that paste only has a few hours of working time once it's applied, so you have to assemble it in the day.
