Teshuva, Tefilla, Tzedaka Mavirin es roah hagizera.
You do teshuva yourself, you dont pay anyone to do it for you (nor can you), so, daven yourself and give whatever amount of tzedaka you can, to any worthy cause.
Chazal never stipulated that only tefilla by specific tzadikim, or specific amounts of money will be mavir es hagizerah.
