IR filter conversion DSLR

[TheMan]

I currently own a Nikon D3300 and I am thinking of sending it to the local camera shop to convert the IR cut filter to a 700nm. I plan to only change it so I can clean it and so focus on lenses will still work. But the one thing is that I would like to do regular photography as well. Will a 700nm filter make sure i can still do regular photography like I would with the stock filter? Is there a different size filter I can convert it to so it gets the best of both worlds? Is there a clip in IR filter for it? Or is there a way to correct the infrared in post processing? Any help will be greatly appreciated.

You should be able to balance the colours in processing, or setup a custom white balance if needed.

How would I do that in photoshop, or other software? could I use auto tone? Or would I do something else?
