[spoiler] Heres some help for the hard badge. Day 1: Bounce once and buy acceleration. Day 2: Bounce twice and buy acceleration. Day 3: buy glider and ramp height. Day 4: get the height and glide mission. Buy 3 more ramp height and 2 air res. You've completed the 5'ramp now. Day 5: get the height and glide on 10'ramp. This was how I begun (17 days). Know what you buy... Ramp height helps you getting the height and glide missions. Acceleration is only usefull when it doesn't exceed your speed limit, but is very valuable. Hope it gives some confidence to get the hard badge too.

day 8: buy fuel #5, 35` ramp, get height + time (same as day 3 but drift down at 15mph)
day 9: buy the 3rd glider, 20` ramp, distance + speed (same as day 7)
day 10: buy ramp height #8 + acceleration #6, 35` ramp, distance + speed (use your rockets immediately and go down a bit to get the speed achievement but don't hit the water)
day 11: buy air resist + fuel #8, 50` ramp, height + time (same as day 3 but drift down at 25mph)
day 12: buy acceleration #8 + the 3rd rocket, distance (4000)
day 13: buy ramp height #10 + fuel #10, WIN (6000)
for the last 2 days, glide at about 2% air resistance and keep your speed between 185mph and 200mph(don't go over), then stay just above the water for as long as you can.
also you don't have to get the speed achievement on the 50` ramp to clear the game.

Holy Shit I did it!! With lots of days of practice, I did get the hard badge. Just followed the guide bellow:
day 1: collect 17$
day 2: buy acceleration #1, get the distance achievement, 55$ (lean forward after first hop to bounce twice)
day 3: buy the glider, get the height + time achievements (go straight up, then lean forward so that you don't go under 5mph (don't stall), then drift down at 10 mph)
day 4: buy acceleration #3, go on the 5` ramp, get the speed achievement
day 5: buy ramp height #4, get height + time (same as day 3)
day 6: buy the rocket + fuel #2, go on the 20` ramp, get height + time (same as day 3)
day 7: buy the 2nd glider + air resistance #5, 10` ramp, distance + speed (for distance, glide just above the water and don't bounce off it or go into the red zone)
