A common practice is to ask for a percentage of the money up front (especially if you will be doing a lot of work for the client, what this does is insures you will be paid something if the client goes MIA with your work and also means that the client is serious). From what I understand the client wants your illustrations for the book and to use them for advertising and in different respects but to pay a flat fee for everything. You should clarify if you are ok with this before hand and have it written into the contract if not that if the client decides to use your work in other places than the book he will be able to as long as he pays you X amount. Something along those lines, as for the physical signing I think it would be ok for the method you wish to use, but I would research that.
