Hy Guys. Why are we talking about "buy services" here? I thought that this was a "Joint Venture" site. In joint venture, nobody should be expected to buy anything. Buying and JV are contradictions in terms.
Venture means a journey where the outcome is uncertain. Joint venture means a journey taken together, both looking out for each other and sharing the spoils when success comes.
When you are selling something to another person this is not a joint venture. The only one venturing here is the the person purchasing that service or product. I am not sure that you have any business at all here to be quite honest with you.
