Not likely since 35 kHz. appears to be an unusual value. Cutting a custom crystal for this frequency will be expensive. You will have better luck with a higher frequency oscillator and a frequency divider. You also might have better luck if you work with a programmable PLL (Phase Locked Loop).Are there any oscillator board having the provision for giving the crystal input of the range of 35khz available for purchase?
If we have the crystal unit for that frequency, are there any board available for giving my hand crystal input to that board?Not likely since 35 kHz. appears to be an unusual value.

It may be possible to find a board that uses a watch crystal with a frequency of 32.768 kHz and take that crystal out and put yours in. If they are the same type of cut, then you might succeed. If not, then you'll need to try something else.If we have the crystal unit for that frequency, are there any board available for giving my hand crystal input to that board?
Square wave output with high precision and accuracy.Crystals with frequencies of 34 kHz and 36 kHz are available through Digi-Key. They show a 70 kHz crystal, but no stock.
They do have a 70 kHz complete oscillator IC in a surface-mount package:
If you can find an oscillator IC with the right frequency, here is a mounting board for it:
Your question is difficult to answer because you have given us very little information.
What are you trying to do?
Do you need a sine wave output, or is square wave good enough?
What frequency accuracy / precision / tolerance do you need?
How many pieces do you need?
Several companies make programmable silicon oscillators that might be good enough, depending on you actual requirements.
A "crystal" for that frequency is a tuning fork, not a real crystal. These have limited accuracy and poor temperature effects. For any real precision (is the spec a secret?), you will have to start with a higher frequency crystal osc and divide it down.Square wave output with high precision and accuracy.
