1. "how much of a hurry you are" → "how much of a hurry you're in"
  The idiomatic expression in English is "to be in a hurry." Additionally, the contraction "you're" is more natural in conversational English. The preposition "in" is required to complete this phrase correctly.

2. "If you are hurry" → "If you are in a hurry"
  "Hurry" is a noun in this context and requires the complete phrase "in a hurry." You cannot "be hurry" as "hurry" is not an adjective. The correct expression requires the preposition "in" and the article "a" before the noun.

3. "How are you hurry in?" → "How soon do you need it delivered?"
  The original phrase is ungrammatical and confusing. The corrected version "How soon do you need it delivered?" is the standard way to ask about timing requirements for delivery. This phrasing is clearer, more professional, and directly addresses the customer's potential time constraints.

1. "in case of regular ones" → "with regular service"
  The phrase "in case of" is not appropriate here as we're not discussing a hypothetical situation. "With" is the correct preposition for describing a service option. Additionally, "service" is more precise than "ones" and maintains proper parallel structure with the previous mention of courier services.

2. "regular ones" → "regular service"
  Using "ones" is vague and informal. "Service" is more specific and professional, maintaining consistency with the business context of shipping services.

3. Added comma in "2,000"
  In English numerical notation, numbers over 999 should include a comma separator for thousands to improve readability. While some countries use different conventions, in English-language business communication, "2,000" is the standard format.

4. Added "the" before "latter"
  When using "former" and "latter" as pronouns referring to previously mentioned items, they should include the definite article "the." This follows the standard English convention for using these comparative references.

1. "In term of" → "In terms of"
  The phrase "in terms of" is always plural in English. This is a fixed expression used to introduce a specific aspect or category being discussed. The singular form "term" is incorrect in this context.

2. "more questions" → "other questions"
  While "more" is not strictly incorrect, "other" is more appropriate here because it better indicates additional or different questions from what has already been discussed. "Other" suggests a continuation of the conversation while acknowledging the previous questions that have been answered.

1. "How would you like to send them, express courier, regular courier, or ordinary mail service?" → "Which service would you prefer - express courier, regular courier, or ordinary mail service?"
  The revised version is more precise and professional. The question is restructured to be more direct and clearer. Using "which service would you prefer" is more specific than the vaguer "how would you like to send them." Additionally, the use of a dash helps to clearly separate the question from the list of options.

2. Added comma after "regular courier"
  In a series of three or more items, a comma (known as the serial or Oxford comma) should be placed before the conjunction "or." This ensures clarity and prevents any potential ambiguity in the list of services being offered.

1. "total is" → "total comes to"
  While "total is" is not incorrect, "comes to" is more professional and commonly used in business transactions. It's a standard phrase used when stating final amounts in commercial contexts.

2. "How would you like to pay?" → "What method of payment would you prefer?"
  The revised version is more professional and specific. It clearly asks about the payment method rather than the vaguer "how would you like to pay." This phrasing is more formal and appropriate for a business transaction.
