Postgresql database to openerp

Hi, Our company use Postbooks([login to view URL]) and we would like migrate on openerp. I'll search a freelancer who can migrate all the data from my database postbooks(it's a postgresql database) to the openerp database. There isn't lot of data, 400 items, 150 invoice, 150 purchase order,integrate customer, provider... I need a perfect work. Send me a message, if you have question. regards, Wavemill
