If you have a low $xxx offer, then maybe you can convert it to a high $xxx offer.
I doubt you'll have more offers in the future. If you do, they'll be infrequent. Best-case scenario for this name is probably around $2k. If it were me, I'd probably make a $2k counteroffer and see where things go.
I wouldn't consider this a very good domain, honestly. But if someone wants to use it, let them buy it from you. You won't realistically be developing it yourself.
