That's confusing from the buyer's standpoint. I would contact you only if I feel that this domain is 100% of what I need, and nothing comes close to it... In case of alternatives I'd keep browsing, assuming that you need this name (since there is no visible indication that it might be for sale).
I wouldn't redirect if your main goal is to sell it. However, if your goal is a good link and you believe in traffic and SEO rather than selling - then sure, go for it.
