bulk email sending

i need to send around 10.000 emails per month to subscribers. i need to be able to either send it from my software or to use your panel. i need 1 attachment and some text - max size is 300kb per mail all emails must go inbox to yahoo and hotmail. make me an offer in PM and don't put up general text. only after testing the system you will be awarded. emails must not contain anything else other than my text. email read tracking would be good too. looking for a long term relationship.
