Hi,dear. I am a senior software developer. I have just checked your project report, I am able to perform this task with my developer team. I am looking forward to your proposal...

I am an excellent JavaScript developer. On Ebay I will develop a Merchant detection script which would display a Banner or whatever you mean by box. Depending on what state you have the database in I would proceed from there. Google App Engine is pretty reliable and free outside of massive over usage so that may be a place where we can host the database.
