Ibscom, if you are talking about a press release to get links then sure write it yourself and submit it to sites, a lot of people would say the quality doesn't really matter if no one is going to read it.... Personally I would say it will have almost zero positive effect for your business as well as (imo) being half arsed way of going about doing a press release.
Anyway you only need one link to get your site listed. If you don't have the time or a decent idea for a press release just do a link exchange with someone....
