Capacitors selections for proper bandwidh
Can you help me?


You are not going to get reasonably low distortion with a gain of 250 with your front-end transistor circuit. Try splitting the gain into two sections and cascade them so that each has a gain of about 16. Don't use emitter resistor bypass capacitors to get high gain - you get crappy distortion and noisy outputs.

In fact, I don't know what you are not considering an op-amp to give you the gain stage; An OPA209 op-amp would work rather nicely as the gain stage.

Of course, what I would find objectionable in terms of distortion may be perfectly fine for someone else.
