Please recommend an indoor pen

I am thinking of getting an indoor pen for the bunny found at my sisters who is staying at my house until at least next Tuesday unless he is claimed before then. I really want to give him more room but it isn't possible to have him free range in a room. I would like it to be cheap if possible because he's only here temporary and from somewhere with quick delievery if possible, any ideas?? Thankyou

Something like this?
