I need someone to amend my prior artwork on powerpoint

I HAVE a 405 slide powerpoint that i want someone to customise the notes sections of all the powerpoint slides.

It will take quiet some time but the instructions are given if you follow them you ll find it really easy but its a lot to demand from someone , so be warned that its a lengthy process to completion.

If this sounds like you then please write to me.
The powerpoint slides are all basic game designs and templates that need organising and tailor and modification.

I need someone to use there discretion in amending certain slides with instructions given on the original note section your role is to take the instructions and apply them to all slide designs.

You will need to explain to me how i can send it over to you because I'm not sure how you do that safely and securely.

Please write back with your proposals

thank you
