Cash4U.com I know domains like this one break rules - with both a numeric and letter substitution - but it is short, snappy and brandable. I think also if you were told this domain name orally you would probably think and type cash4u.com rather than cashforyou.com anyway, without having to have it spelled out.
Hmm I say less than $250 but you should get a real appraisal if you think its worth a good amount. I suggest sedo appraisals
I can n’t predict about the exact suitable price ranges. But I can see good potential in this. For me good $$$/+
Even though the "4u" hurts this name a lot, this is a great name that could go for in the Mid to High $xxx range IMO.
