CATALUNYA need base for our bus to explore and purchase property

hello
we have sold our 7 acre smallholding in east yorkshire keeping 2.5 acres of land to park when in england.
for the past 12 months we have converted a double decker bus into a motorhome for ourselves the two children (under 2yrs)and our dogs.we are currently looking for a base to park the bus (approx 1 month)so we can explore the catalunya area looking for the right finca/land to purchase.electricity/water would be helpfull but not essential as we have a generator, a quite spot would suit us best as we have dogs.looking to move out at the end of the month.
we would be grateful if you have a space for our bus or know of anybody that could help.we would pay for the privilege.
regards
steve and jo
