You do not need a brief or a spec to ask for a quote. Most requests start with a few lines: what you sell, who buys it, where you advertise now (if anywhere), and what feels stuck. If you have a monthly ad budget in mind, mention the rough range in words. If you do not, say so. That is a normal starting point too.
Specific notes get a specific reply. A request that says "Google Ads for a commercial cleaning company in three states, and calls go to a shared inbox nobody watches" gets a far more useful answer than "need leads."
Details worth including
If you only have a minute, cover the first three. The rest help with a fuller quote.
- The service from the list on this site
- Your website and what it sells
- The email address for the reply
- Ad accounts you already have
- Analytics and tag setup
- Your CRM, help desk or lead inbox
- Who answers new inquiries and how
- Anything a previous provider left unfinished
The first reply
The first message you get back comes from the service partner who would do the work. It usually asks about the gaps in your request: what a good lead looks like for you, what the ad budget is, who has access to your accounts. Answer what you can. If you do not know something, saying so is fine.
Some partners like a short call before writing a proposal, especially for accounts with history. Others can work from email. Either way, the proposal comes in writing so you can read it properly and compare it with other options. Accepting it is up to you.
