The date your employment terminated your status terminated. Your ESTA is not a determination on admissibility. 8 U.S.C. 1187(h)(3)(C). Your VWP attempted entrance is in B1/B2 status. INA 217. You must have the intent to depart and not to violate the terms of that status. You must overcome the presumption of immigrant intent which includes an entry for the purpose of seeking employment. Your plan is not a great idea.
All I can say is that you can 'try' to get into the US ... there is no guarantee.
Have better proof of your plans to 'pack-up and move-out' than job hunting when you enter.

When you come with you ESTA you need to prove non-immigrant intent. Saying that you are comming to look for a job could affect your non-immigrant intent before CBP officers. If you are just coming to wind up things here you should be ok.
