I wonder why they are not replying. Also, I doubt that the email you've sent them are on a formal manner based from your post and response on this thread.
To be honest, Are you really expecting a reply from them? Don't you think that your email has been directly sent to spam?
Well see that also i can contact them by phone or worse case scenario i can visit their office
No shame about it if you want money.
There is no need formal manners...just money talk how much when and how thats it. We all here for $ we understood each others well they want $ i want $ im greedy they are greedy thts it.
Lets see the reply
Let's see if they'll even answer your phone call if you try to do so. Also, your worst case scenario will really be the worst case scenario as you'll have more clarification that will not be interested on your offer.
No need for formal manner? I wonder if they will take you seriously knowing that you only have "money".
