PLEASE I need help today! Many thanks :)

I got an email from a recruiter asking me to call him back to discuss further. I think he doesn’t know that I am not in the England at this time, and I want to reply him and tell him that nicely so that he doesn’t change his mind about considering me for this position or any future openings. English is not my first language so I would appreciate any suggestions or editing. Thanks a lot ?

HIS EMAIL :

MY EMAIL :
Dear Mr. R,

Thank you for contacting me about the Technical Support Specialist job opening. I am interested in this specific opportunity, it appeals to me as it combines customer interaction and training with technical support responsibilities and practical responsibilities.
I would appreciate if you can send me some more information about the company's product and instruments or the company's website.
Also kindly be informed that my UK visa is expired, I am originally from Jordan, but I am willing to relocate and get a new visa and I will take care of all expenses associated with my visa if I am offered the job. Please give me your Skype ID to discuss further if that is convenient.
Furthermore, I am ready to have an interview with your client through Skype if you think that my qualification meets his requirement. I could also come to the UK for an interview if the company requires that.

Thank you for consideration and I look forward to hearing from you.

Kind regards,
N
