Quite a few people, myself included, have warned that a PPL(H) could take 70-80 hours; if you can't budget for that now plus all the incidental costs which can amount to a few grand as well, then you do need to consider whether you can complete it. And. after you've completed, can you afford to maintain the licence flying, say, an hour a month.
However, your job is such that you could fly for several hours a week and reduce the timescale that way. This may reduce the number of hours to completion but only by a few percent.
If you really want it, you'll find a way but you may well have to reorganise your finances!!
