Hello, I apologize for the unexpected inconvenience. I was looking for a possible trade since I have an offer for you; can you add me? I am willing to overpay a little bit.

I'm sorry for disturbing you, but I'm unable to add you right now since I'm running out of invitations. Could you please add me for a trade? i have a nice offer and I'm prepared to overpay a little bit for a deal.
