G'day mate,
My name is Mat from Sydney & I'd love to build a website for your migration agency business. I've had a look at your requirements and I don't foresee anything that will cause any issues. To address them separately:
1) responsive website - all of the websites I build look great on desktops, laptops, tablets, smartphones etc.
2) unique call to actions - this isn't a problem. I recycle pages so unique content and CTA's aren't an issue.
3) Blog functionality - I'll be utilizing the open source WordPress platform which is great for blogging.
4) Easy for you to manage - the website I build for you will have an extremely powerful backend admin panel where you can edit content, change photos, adjust pages etc.
5) Landing pages for different cities/suburbs - I don't have any issues creating these pages however you will need unique content for each page so you don't get penalized in Google; can you let me know how many of these pages you're after?
Few questions mate:
a) you mention you have a sitemap, can you send it through?
b) have you purchased a domain name or web hosting yet?
c) have you decided on a name or had a logo created?
Quickly about me mate: I've been here for 10 years, average a 5 star rating, have had my work featured all over and have been nominated for Freelancers 2018 "Solo Freelancer of the Year" award. If you want to work with the best, that's me. Shoot me through a message & let's have a chat.
