Need Advice Before Selling a Site

I'm considering selling two sites, but I'd like some feedback before I actually put them (especially one) up for sale.

The site in question is www.AllFreelanceWritingJobs.com

I only launched it in April. For its first month it made around $15 through Adsense and Indeed.com ads, with quick daily (or at least frequent) postings of 10 links to freelance jobs posted online... not hard to maintain, but I'd rather offer the feature on my bigger writing blog, and spend more time on bigger sites than this one.

It's predicted to go to PR5, which is what my two older writing sites did on their first updates as well... the predictions tend to be pretty accurate for me so far.

So I was thinking it might be best to wait until the site has PR, and then sell a few link subscriptions in the sidebar and/or footer before putting it up for sale to ensure income for a few months. I have no doubt, I could have it at at least $100-300 / month by around that point with monetization methods combined.

The other income stream would be individual paid job postings from employers. I just launched the service, and have it free until June 1st, at which point it would be $10 / post, so I was thinking it would at least make sense to wait until the end of June to sell, so I can show revenue, if any, from that service as well.

The question

Do you think it would be best to wait until the end of June, so I can show revenue on post sales, or would it be best to wait until after the next PR update where I could sell link subscriptions too? Just not sure if I want to keep updating it all summer, but I will if it would be best.

On a sidenote, I was thinking of offering a sort of "value added" deal with the site sale... like a press release announcing new ownership that the buyer could distribute (I normally charge $99 to write one), keeping my own links to the site up through the following PR update, maybe having someone create a custom logo and/or hiring someone to do some directory submissions for them (I've never made a link building effort for it before... just natural links mostly from my other writing sites and people who follow me from one to the next)... I dunno... was just trying to think of something that might help if I did decide to unload it earlier instead of waiting. Any thoughts?
