4 short press releases needed in 48 hours. Experienced press release writers only

As above, I will provide you with the subjects of 4 press releases (all related to one service). I need you to write me 4 short ORIGINAL press releases of 500-700 words each. As they are only short my maximum budget is $4 per 500 word press release but there can be ongoing work for the right person who gives me a good price this time. I need these press releases to be of a very high standard so please only experienced press release writers shoukld bid. You *must* supply *press release* samples in PMB to be considered for this project. I will be selecting someone soon so bid quickly. To make sure you have read all the details, together with your PMB press release sample, please write me a message which explains briefly what you understand to be the differences between how articles and press releases should be written.
