Yes, there is no problem on that.
We can arrange meetings via Skype and any remote access program you are familiar with (we can recommend a lot) . We will be working on your computer remotely. In that way, everything will be ready to you once the session ends.
A high definition camera will be used for the drawings via a high speed VDSL line. You can easily take screen shots to store any diagrams we have made.
If you have difficulty setting up a computer, we can provide instructions and finally, if needed, come at your house to help you setup it up.
