Planning to launch Marketing Agency, Need your suggestions.

After launching uisumo, Two more guys joined with me , who are good at front end coding.

We are planning to launch a marketing agency, where we can offer :

1. Landing Pages - Design to Development (A/B Versions)

2. Email Templates - Design to Development (A/B Versions)

3. Google Web Designer Ads

But, We need some expert advice to choose either of the below strategy

1. Package System : Where we can offer a complete set including a landing page, email template and a set of Google ad banners.

Packages like $99/one set , $149/one set with Split Testing Versions

2. Traditional Way: Where we design based upon client's requirements.

Thank you all.
