请帮助正确翻译一下【中翻英】：
你好，好久不见，不知到你在下周一之前是否有空能和我见一面，我有一些紧急的问题可能需要你的帮助，我想我不会占用你太长的时间，也许一个小时就足够了。如果你能够帮助我，我将会非常的感激。感谢。

请不要用机器翻译，也不需要和中文完全一模一样，意思表达到就行。

我的翻译是：
Hi, haven’t seen you for a long time, how are you? Just wondering do you have time before next Monday so I could meet with you? I have some urgent issue need some help, it would not occupy you a very long time, maybe 1 hour would enough. I would be very appreciated if I would get help from you this time, best regards.

请在我的翻译的基础上纠正一下。
