You should take into account the use of the input and output capacitors of 741, if the entry is about 0 ... 10mVac.
If it's 0 ... 10mVdc, then you must change strategy.

 

Why do you need thru hole?

You are working with signals levels that are going to be sensitive to noise. It might be better to use surface mount and the packages available can be done by hand pretty readily.

 

i think it's a little expensive for my application which generate mv signal .

Well, if an opamp that costs $2.57 from Digi-Key in single quantities is too expensive, then I doubt I can help you any further.

 

i found this chip MCP6022 http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en010439 but it's offset is .5 mv , Is this .5 mv should appear in output or it will be from 0 to .5 mv and what does affect this increment ?
Is it constant over some time so i could subtract it of output if it is known ?

 

If the amplifier has a gain G then 'offset x G' appears in the output. The datasheet should indicate how variable the offset is.

You could use a offset nulling circuit, which introduces a compensating offset at the input. The offset varies w.r.t. temperature, which is specified in the datasheet, which is usually quite small in precision opamps.
