Sometimes the city or town you live in can assist people in paying their rent also. You may have to jump through some hoops but it's well worth it in the long run. There are also churches that are there for help too. It doesn't matter if you are a member or not...they help anyone in need. You can also try calling your local Community Action program. If they cannot help you, they can point you in the right direction.
Wishing you luck skittles...I know how stressful this can be. In the meantime, it might be good to let your landlord know you are a bit short but working on getting the $300. If you have some of the rent....I would give him what you have. There are tenant laws that will help you so that you are not evicted while you are working on solving this problem.
