Create Backlinks for new project

I need a freelancer to help me create backlinks for a new project. I have specific websites or publications in mind that I want to target, so the freelancer must have experience with creating high-quality backlinks. I am looking for 250-300 backlinks to be created, mainly with directory submissions and guest blogging. The freelancer must be highly experienced in SEO and link building to ensure that the work is carried out to a high standard and with a good turnaround time.
