leach field dilemma

I thought when I found out that our septic system had failed that I had enough money to fix this myself.  Little did I know as I started the process that this was not going to be a cheap fix.  I have stressed over this for weeks, and the last straw was the bank telling me sorry for your luck and I should ask a family member or friend for help.   I just found out today that the equipment rental alone is probably close to $2000.00 that is almost half of what I have saved for this.  I don't know how much I actually need since I am doing it myself, I will say whatever is leftover from this I will donate to a local charity, I am not looking to make a cent from the gofundme page and I feel very uncomfortable even doing this.  I just want to be able to flush the toilet and not worry about where it is going.  Thank you for even reading this.
