Need Home Equity Loan or note from Lender or Investor for Rehab + Bus. Investmen

Hi, I am hoping to find an investor or lender that can help with a equity loan on my home that my wife and I are purchasing on a note and have been living in for three years.
The balance of note is aprox. 45,000 property should apraise at 80-85,000.I want to do some rehab work on home to help raise value and equity.I was a licensed general
contractor for ten years and have done all phases of renovation and repair work on rental properties for realtors and investors previously.I have the knowledge and ability to
do quality improvements for a fraction of a contract price doing work myself and discounts on materials.I just recently replaced roof on home complete with new plywood.
Neither my Wife or I have the good credit due to many factors and our scores are low.We have recently applied with a mortgage company that siad we where approve and
set a closing date and then ran our credit again and said our scores dropped because of inquiries.We now are in a difficult spot and don’t know what to do.We are willing to
pay higher interest due to our fica score because the money will be reinvested into business expansion for our transport corporaton and another single residential property
we purchased on a note for 25,000 and want to rehab and flip.We will secure invetment or loan in any way we can and would like to pay off short term.Please help with any
advice, info. and/or offers.
