[Grammar] And then I made a deal. Mark would convince Kevin

[Nikitus]

Hello.

Are the following sentences grammatically correct?

And then I made a deal. Mark would convince Kevin to make another video explaining that all was a “inside joke” and I would help Kevin to go on with his life, performing a "ghost"

Thanks.

Thanks.

See above.

Dear emsr2d2:

Once again, thanks for your help.

The woman speaking, will use makeup and with help with other persons that will help with special effects, she will perform a ghost. Kevin, the person who will "see" the "ghost" will be drunk.

Thanks.

I think you mean she will play the role of a ghost. You can't "perform" a ghost.
