I'm launching an SEO-As-A-Service Business – Will it work?

I am currently putting the finishing touches to a side project where I am offering SEO products on a buy what you need model, through an online store.

I am interested to know if you would use a service like this and what services you would like to see on there.

Currently have products around link building, press releases, technical SEO auditing and more.

Just interested to hear some thoughts.
