Need help with guest posting

I need help with guest posting. Need guest post for my niche site. My niche fishing. It would be great if you can do guest post for me on fishing site. If you don`t have any fishing site, I am okay with Travel, outdoor adventure type site if they have enough organic traffic and back-link. I will provide you content. you just need to publish with my link. Price negotiable if you can provide good site. Want to start with 5 post. If you can provide quality link then we can work for long term. Thanks
