I have over 25 years experience with data and information processing in a large SE European survey company; rcently I decided to work as well as a freelancer.
I may be wrong, but it looks that your post is on the wrong page - you are not buying services, you are, more likely, selling....
If this is not so, meaning that you realy need some freelancers to work for you, I am realy interested.
If this is so, meaning that you want to promote yourself / company as provider, mediator or broker, please be aware that there are costs for any freelancer placing bids to a job offer.... someone, someday, may report your offer as an abuse....
Truth is that today on freelancer there is too much abuse.... more from (fake) employers.... True potential employees may be intersted in cleaning off fake potential employers.
I am open to further negotiations.
Thank you for considering my offer.
