Super impose my character into an existing image

Hope you are well. You have done some headers for me already, where you superimposed characters into an existing image. I need the same to be done again. This time with one of my characters which I'd like you to put into an existing image. Please quote me first before I send the files.

Also, don't know if you can help. Again, I can't find previous work you did for me. and I can't see it on PPH either so I can re-download them. This time I have an external disc drive, so when you send it to me, I will save it there straight away to keep it safe.

Look forward to hearing from you at your soonest convenience.
Thank you so much.
