the longest I will hold a space is 2 months and that is with a deposit. If my area could support the idea, I would charge a holding fee, however no other provider does that here so there is no way I could.

i would do as above suggested, offer to contact them in a few months if something is still available. Alternately, if you are just getting started, you could use one spot to 'hold' and try and fill the other two.
