Help me to save my shop and house

I am a wedding and portrait photographer based in dar es salaam, tanzania. recently the economy crises have raised and i was effected by loosing some savings as i had invested in one of the company which went bancrupt. I am in a situation where i might loose my shop where i do provide photographic services and my house where i and my family stay together. Each month i pay for shop and house rental which costs USD 625. I just need to the total rental of 4 months as i believe i will be back in my position to continue paying for the future. I am asking this amount in exchange of my photography services. The only difference is that the person who will help is by paying me of my services in advance and not after the delivery. I will be very greatful to the person who will help me out on this situation. And i promise to give my best of service to that person. I really hope to find the help at the soonest as my deadline to pay the rent is by end of august.
