You can resubmit when the new site is finished. If the editor judges that the "primary purpose is (still) to drive commercial (e.g., affiliate) traffic to other sites", it still wouldn't be listable.
The editor's judgment will inevitably be affected by experience with similar sites. And many affiliate marketers are fluffing up their sites with promotional material merely to pack keywords in for search engine spider bait. So your "content" would reall needs to look like "information", not "promotion", its main purpose really needs to not look like enticement to buy; it really needs to be substantive and even unique on the web ... or the site will just look like the disguise du jour for deceptive affiliate marketers.
Many people, even with the best intentions, find these criteria extremely difficult to master: either they simply don't know anything unique, or their writing style is trapped in the imperative rather than indicative mood. (Most of the writing most people have seen is promotional in nature; other forms may therefore be difficult to write.)
Look at your writing this way. (1) Suppose someone is not interested in determining whether or not to purchase your service. Is there any conceivable value that they could get by reading your material? (2) Suppose someone is interested in buying the service. Can they be dissuaded by reading your material?
If the answer to either question is "no", what you have is clearly promotional material with the primary purpose of collecting customers (for other sites.)
