Design an amplifier circuit with 100V output on a 1K Ohm load

I am looking for an electronics or electrical engineer to design a circuit for this small project. I am looking for a good circuit designer as I am planning on advertising more projects in future. Current project: I have a circuit which produces a 40Khz (sort of sine) wave which oscillates at +0.8 and -0.8 V, please see attached files. I need an amplifier circuit designed which will reproduce the sine wave with an output of 0-100V peak to peak. The output load is specified as follows Center Frequency 40.0±1.0KHz Bandwidth(-6dB) 2.0KHz Nominal Impedance (Ohm) 1000 Ringing (ms) 1.2 max. Capacitance at 1KHz ± 20% 2400pF [login to view URL] Voltage 100Vp-p @20 bursts, 25 ms repetition rate The circuit has a 5VDC supply and a 100VDC supply which can be used for the amplifier. The load will be pulsed 5ms ON 45ms OFF. The circuit should provide input to allow for this i.e. 0V turns off load and 5V turns on load. The sine wave amplitude should be able to be controlled by a variable resistor so that the output is 0V to 100V. I only require the circuit design with recommended part numbers. I do not require the circuit to be physically built. I do not need to see the simulation as long as you are confident that it works. OPTIONAL: If you throw in a DC to DC converter which takes around 3V - 15V DC input and converts to 100V output which can drive the load (with some overhead) then that would be good but is not mandatory. Any suggestions on how to clean up the input 40khz sine wave or any other general comments on the circuit would be appreciated.
