Yes you can hire someone to do this. But be careful because sometimes they can do more harm than good. SEO services can be expensive or cheap. It depends on what you want to achieve and how much you want to spend. The most difficult part of this equation is finding someone with a good reputation.
Simply building links for your Hub is not a good idea. Not the way this is normally done. Find some nice PR sites that are dofollow and point them to your hubupages. Try blogmyway.com for starters. Point blogmyway to your Hubpages (only a few). Use a bookmarking service online and build up your bookmarks. Your Hubapges should do very well this way. If want send lots of links to blogmyway. Blogmyway will get stronger and send lots of Google juice to your Hubpage. Also when you use a property like blogmyway you protect your Hubpages. That property acts like a buffer while sending Google juice to your Hubpages.
I do SEO for people. It is always necessary to look at the whole picture before giving a quote. A word of caution. Do not just take the lowest quote without doing some research on that person first.
There is lots of good advice here.
Any fool can give you 1,000 links but do you want to take the chance of running into issues with Google? Use a buffer!
