Help laying our dad to rest

I am not quiet sure how to go about this.. My family, siblings and I are trying to plan a funeral for our dad ( Randy Sifers )that just passed away in a horrible accident.. We got the break down for funeral costs and it totals around 5,500.. The casket was the same one as our dad and his sisters chose for their dad a few years ago! It is difficult to find a way to afford this within the amount of time he deserves to be laid to rest in.. The funeral home said we must pay in full... We are feeling a little lost and hopeless. Anything helps and we are more then greatly appreciative.. Thank you - Cyndra, Stacia, Cody, & the entire Sifers family!
