Desire to purchase a gently used mobile home from Illinois or a closely neighboring state

As stated above, I desire to purchase a gently used mobile home from Illinois or a closely neighboring state.  Preferably, from within Illinois.  However, the closer the better as far as neighboring states; due to transport costs.

I will need financing or some sort of payment arrangement because we are already paying on land while performing a sudden relocation (was already in the works but was unexpectedly pushed up by landlord selling home after claiming it wouldn't be soon).  Going into the nest egg, so my ballpark maximum is $7000-$10000 (with payment schedule/QuickBooks ).  I'm a caregiver, so this would be much appreciated.  

Thank you.
