Desperately Need Tent

Hello neighbors...I am looking for a tent that is large enough to hold my husband,me, my 19 yr old and his dog, and then my 4 and 7 yr old. Yes I know that's a lot in a tent but that's our little family:) we were offered a chance to go on a camping trip that we ourselves would normally never be able to afford and I cannot think about having to pass it up due to not having a tent. Alot of places are either a) sold out or b) want 100+$ which I can definitely not afford right now. I am barely making it by check to check. A little back story...a friend of mine I went to school with and have stayed touch with over the years just happened to see me at the grocery store the other day with all my kids and she has kids the same age. She tells me she is going on a camping trip that will last 6nights and 7 days and she has 2 campsites right along the rifle river up north. She has tubes for all of us and said she has most of the food and drink covered but I have to come up with a tent as she doesn't have an extra one. Everywhere I have looked for a tent that will hold us all(avg 8-10 person tent) they want almost $200. And the used ones I see on marketplace on FB the cheapest I have found is 100$. I don't have that kind of money. The only tent I can afford is a little 2 person dome tent and they still want anywhere from 45-75$. I was hoping someone on here might have an old one in their garage they know they won't use again or even any time soon and would be willing to sell to me for cheap. Or even possibly let me borrow it and I can pay like a loan fee I think it's called.
