Brand new start up business loans

[Cameron Hume]

My two best friends and I are planning to start a construction/rehab business . I have the most construction experience, as well as they aren't new to the type of work. I have the lowest credit score at 605/620. The other two I believe are about 680 and 700 I believe. We even have pur first job lined up, a house a friend bought to flip and the old contractor just walked out on her. (Idk if this is the correct place for this question(do we do a llc or partnership to start the business and get our ein)) and is there start up business loans that we could qualify for with our credit and projected income to buy equipment and other business supplies ? Thank yall in advance for taking the time to read this and share your knowledge
