Are any of the following correct?:
1.- Let me know when it's more convenient for you me going to your office.
2.- Let me know when it's more convenient me going to your office for you.
3.- Let me know when it's more convenient for you that I go to your office.
4.- Let me know when it would be more convenient for you that I should go to your office.
I think 4. is correct, but I would like to know so are any of the other possibilities (especially 1. or 2.). They seem less formal and might be more appropriate depending on the context.
PS: I have added the subjunctive tag because in Spanish that would be a present subjunctive form. If 3. is correct I will ask a separate question asking what happens if ''I'' is replace by ''he''
