I am prepared to help you, yes, but I cannot give any guarantees. I am prepared to look at your site and talk with you (even if your English is not all that good); I have a reasonably good basic understanding of other written languages such as French and Spanish. We may be able to resolve the problem fairly easily.
I generally operate on people giving me a deposit to commence looking into problemsl. This gives people the incentive to work more co-operatively. If the solution requires the investment of dozens of hours then I will give an indicative estimate of the total final cost and issue an invoice as appropriate. However, let me make one thing perfectly clear: this is the Kunena forum—where people can ask questions and hope that someone may help them (at no cost)—this is not a place for people like me to advertise what I do commercially.
Everyone knows what I do and where I operate my business. This is all I have to say at this time.
