Dear Sir / Madam,

Which one is comprehensible and make sense, If possible please correct them as necessary.

1. Security Service Contract
2. Service Contract of Security Maintenance
3. Contract of Service for Providing Security Maintaining
4. Service Contract for Providing Security Maintenance
5. Service Contract for Providing Security Protection

Those are a name of a contract or an agreement between two parties. it is a contract for providing security guards to a company. Which one of those is the correct title of the contract, or what is the proper name of contract of this type.

Thank you in anticipation.

Best regards,

3. is not it better to use "maintenance" instead of "maintaining". Otherwise it sounds a bit clumsy for me...

Thank you Bernadetta, but it is not clear to me if those are correct or make sense to you or not. You mean 5 of them are correct, except item 3, you mean to say that I should use maintenance instead of maintaining, don't you?

Please give me more details or correct them for me.

Thank you and best regards,
Piak
