Agree with Arv,
Soldering surface mount is easy. It only gets hard when you have
really tiny chips with lots of pins... and even then it's not THAT hard. You basically run your iron and solder along the chip pins. Everything gets soldered together. Then you take solder wick along the chip and it sucks up all the excess solder.
In general, you don't depend on the flux in the solder - use a flux pen on the board first. Makes things easier.
I have a cheap Chinese hot air rework station and a stereo microscope. With those, I can solder pretty much anything except for giant BGA ( Ball Grid Array ) parts.
There's a reason why modern electronics is 90% surface mount.

It seems that many hams prefer to discourage the rest of us from
soldering to SMD components. In truth, after an hour or so of
practice it becomes rather easy. For connecting wires to an SMD
device I use small (AWG-20 or 22) coil winding wire. The laquer
coating serves as insulation and the small wire size makes it easy
to tack-solder to the IC pins, and resistor, or capacitor ends. SMD
standardized component size makes it easy to stack components
vertically or horizontally. Farhan laid his components flat on the
substrate, but it is interesting, and maybe easier, to place resistors
and capacitors on-edge.

Just to impress you people, this is on my bench. A ugly build of
Si5351 using a low noise 25 mhz oscillator. All hand soldered. I
bend alternate pins up and down and solder the ground and vcc to
the square pads.

How in the world were you able to solder the SI5351 ?
I am very very impressed!
