I need a Sports Writer(s) with link acquisition expertise

Do you already write for a Sports News website? Are you in a position to post links onto a webpage to direct traffic to another site? If so, please apply! I'm looking for someone to secure links to my client's site, either by integrating them into articles as anchor text or simply posting them as a clickable URL. It's easy as that. There are a couple of stipulations (such as a max number of links per site etc.), but I can discuss these with the successful candidates. Please note that there will also be opportunities to earn bonus payments for posting links on certain websites. ****EDIT**** PLEASE READ BEFORE APPLYING!! I've had some applicants who don't seem to fully understand the remit here, so thought it was best to clarify. I don't write any articles for you or create new relationships with sports news sites. The idea is that the candidate already writes for sports news sites, and is therefore in a position to integrate links into their work (or somewhere else on a webpage). The payment is $14 per link. Although I'm happy to receive applications from those who write for websites based outside of North America, anyone with connections to U.S/Canadian websites will have a slight advantage! I'm eager to create a positive working relationship with whoever I'm working with, so please feel free to ask any further questions you may have. Thanks!

UK Law concerning Buy to Let Mortgages

I have a situation with the UK mortgage lender where I have a mortgage which needs to be redeemed in my soul name by the 31st of March 2026. When I asked the lender for a redemption figure they picked up on a disputed joint mortgage with a third-party from 6 1/2 years ago which had been repossessed because it had come to the end of its term what they are saying is that they have the right in law to now link both mortgages so when I repay the debt owed on the mortgage in my soul name they will not release the charge until the debt is repaid on the mortgage in joint names. I have questioned this two or three times and they refused to budge I would like advice on whether this is something that would stand up in court given that the two mortgages are in completely different entities, a little information regarding the joint Mortgage since my complaint about the way the repossession was handled 6 1/2 years ago I have not heard from them at all not one letter a statement or any communication whatsoever. It is my belief as this has been written off and that they are now trying to collect this using the security of the Mortgage in my soul name I have been trying to get this matter resolved them for over nine months they are In London! who no longer lends New borrowing they are just executing the old MORTGAGE EXPRESS book. It would be good if I would be able to speak to the successful person to discuss this matter as well as have a written answer as there are some complicated issues.
