Backlinks for 2 websites for USD 30

I have 2 new similar websites that require backlinks. I have a fixed budget of $30. Please tell me in your PM how many and what kind of backlinks you can provide. And as I have two websites, what do you suggest to use the backlinks in an efficient way? Of course, only one way backlinks, already indexed pages, no "weird" pages, etc. Payment: I escrow $30 immediately with the order, and release it as you send your excel report and I check and approve the links. This may be a small project, but I have more websites to be SEO'd :) So please do not send copy/paste information. Instead, write 2-3 sentences of your suggestions about this tiny project. And a good guess: This is a test project :) Happy bidding :)
