we are pumping fuel in hose. fuel of rockets will be pumped from hose realtime.
Where are the rockets, that you are pumping the fuel to in realtime, mounted? How is the hot rocket engine exhaust expelled away from the part of the system lying below where the rockets are mounted?

we can not build space elevator today (no enough carbon nanotube)
we can build my idea today (if it is possible by physics laws and economic at long term), nasa can build my idea in 1 year probably.
space elevator cost 5-15 billion$
i think my idea cost between 400 million$ - 1 billion$. 
Not only is there not enough CNT, there isn't any with sufficient tensile strength to mass ratio.

Neither the time line nor the cost of either system is anywhere near achievable within your estimates. No one is suficiently knowledgeable nor a sufficiently fast learner.

Note that thoroughly answering each of our questions will help you reach the obvious conclusion earlier than otherwise. If the system can be made to work, it will mature much more rapdly. We can not be sure how much of our confusion is due to your english, your lack of thoroughness, or our slowness to learn. A diagram showing each working subsystem in a fully operating system would help.

If you wish to do some arithmetic, maybe this will help.

Vs = Vo + Ve*ln(Ms/(Ms-q*t)-9.81*t*sin(CA).

Where: Vo = initial velocity in meters/sec;
Ve = velocity of propellant in meters per second;
q = propellant exhaust rate in kilograms/second
Ms = KG of portion of system being supported by rocket thrust
t = time interval in sec
CA is the climb angle (from horizontal reference)
Vs will be zero when the system is stationary and whatever value you wish when the system is in motion. You'll need to manipulate Ve and q to acquire the values for Vs that you wish to achieve. CA will vary around 90 degrees and constrain the design of your guidance system.

Power required: ke/sec = .5*q*(ve)^2/(1 sec);

The tensile strength of the rope-hose - f/ meter^2 = (supported KG times acceleration)/effective cross-section in square meters.
