[Useless]

Anyone who has ever worked with me knows that I'm really bad establishing prices, but let me walk you (or anyone who is considering do this for you) through this.

The installation of a WordPress blog is a 5 minute task, and that's if you are smoking and/or sipping coffee while doing it. Unhindered, you could probably knock it down to 3 or 4 minutes. The actual uploading of the files to the server requires the majority of those minutes - that's how simple a WordPress installation is. You login to your control panel. Create a database. Edit your database connection info on the wp-config file. Then upload. Go to the install page and follow the 3 seconds of instructions. Done.

It's the customizing that slows you down. You have to configure the permalinks, kill comments, and install the plugins. (Once who ever does this has done 2 or 3 of them, this whole process will go quite quickly as well.) Modifying each of the templates visually is going to take the most time, especially if you are using different themes and renaming any graphics with keywords/phrases.

Obviously, automatic updates will require an aggregation plugin that utilizes WP's fake cron job or an actual cron job handled through your control panel.

Lastly, you add the sponsor feeds. A cautionary note: many sponsor feeds have been tossed together so quickly [so the sponsor can yell 'we have feeds!'] that many links within the posts quite obviously don't carry the affiliate code. Nice. The state of blog RSS feeds in this industry is horrific. The quality control simply isn't there. I gave up on using sponsor feeds a while back, but Walrus and a couple of others may know of some quality feeds that are more than lists of galleries.

Keep in mind, updating feeds everyday, especially on 50 separate blogs, will bog your server down.
