1997 Ford Aspire CV Boots and Timing Belt Repair

I was told my car needs the front axle assembly replaced (one CV boot is leaking and the other is cracked) and the timing belt replaced because there's oil on it. I can't afford to have all the repairs done at once, but I'm thinking I should have the timing belt fixed first. Would that be the best thing to do? I asked the mechanic I went to and he wouldn't say.
