Hi. I'd love to help you with your site.
I've been developing websites and web applications (large and small, simple and complex) for more than twenty years. Clients have included small businesses, large corporations, and universities.
Please check my profile for examples of sites, applications and plugins I've built.
You don't provide much detailed information on exactly what you need, which makes it difficult to provide a definitive project offer, so this is going to be somewhat generic. As you haven't provided any info on the "service idea", I can't know what is you need or how much effort will be required to achieve it.
My offer includes the freelancer fee, one year of speedy web hosting and dot-com domain registration, and a professional, mobile-ready WordPress eCommerce website with up to 10 static pages of content. Includes SEO, an event calendar, blog and contact form and assumes all content is supplied. I'll also throw in 10 hours of development toward your "service idea".
You'll have access to make updates or add new content yourself after it's launched.
I also have superior professional skills in WordPress theme and plugin customisation, and can even create custom plugins for you from scratch. So if you want to look at a more heavily customised site down the track, or if this is needed for your "service idea" I can certainly help you out.
I'm based in Sydney, so happy to meet up anytime.
